oil painting for beginners: the classical method

oil painting is the most versatile and forgiving medium in western art. for more than five hundred years, painters have relied on it for everything from luminous glazes thinner than a breath to sculptural impasto an inch thick. the medium's slow drying time lets you push paint around, blend edges, and rework passages for days. no other medium offers this kind of control.

this guide covers the classical layered method — the same general process used by jan van eyck, titian, vermeer, and rembrandt. you will learn which materials to buy, how to prepare a surface, and how to build a painting from the ground up through underpainting, dead coloring, and glazing. if you are holding a brush for the first time or switching from acrylics, this is the place to start.

“the painter who is content to copy nature will never produce anything great.” — harold speed, the practice and science of drawing (1913)

why the classical method

the classical method is a staged, layered approach to oil painting. you do not try to finish the painting in one session. instead, each layer has a specific purpose: the first layer establishes the drawing and values, the next introduces broad local color, and subsequent layers refine edges, model form, and add transparent color through glazing.

this is not the only way to paint in oil — alla prima (wet-into-wet) painting is equally valid and we cover it later in this guide — but the layered approach gives beginners a structured framework. it breaks a complex problem into manageable stages. you solve drawing first, then value, then color, then finish. you never have to solve everything at once.

the method was codified across centuries. cennino cennini described tempera layering in il libro dell'arte around 1390, and many of his principles carried directly into oil practice. charles lock eastlake documented the techniques of the flemish, venetian, and spanish masters in methods and materials of painting of the great schools and masters (1847), a book that remains essential reading. harold speed's the practice and science of drawing and oil painting techniques and materials provide the most accessible modern treatment of classical principles.

the core idea is simple: work from lean to fat, from dark to light, from general to specific. every stage is built on top of the previous one, and each layer is slightly richer in oil than the one beneath it. this ensures proper adhesion and prevents cracking over time.

essential materials

you do not need a lot to start. the old masters worked with far fewer materials than a modern art store would have you believe. here is a practical starter kit:

resist the temptation to buy more colors. a limited palette forces you to learn color mixing, which is the single most important skill in painting. for a deeper understanding of how colors interact, see our color theory for painters guide.

choosing your paints

oil paint is pigment ground in drying oil, usually linseed oil. the quality difference between student grade and artist grade is enormous. student paints contain more filler, less pigment, and handle poorly. if your budget is tight, buy fewer colors in artist grade rather than more colors in student grade. the difference in mixing capability and permanence is worth it.

reliable brands at the artist grade level include williamsburg, old holland, michael harding, winsor & newton artists' oil colour, and gamblin. at the upper student-to-lower-artist tier, gamblin 1980 and winsor & newton winton are good compromises.

a note on pigments vs. hues: always buy single-pigment paints where possible. check the label — it should list one pigment code (like PY42 for yellow ochre or PB29 for ultramarine blue). “hue” on a label means it is a cheaper substitute. cadmium red hue is not cadmium red. it will not mix the same way.

the limited palette explained: with titanium white, yellow ochre, cadmium yellow, cadmium red, alizarin crimson, ultramarine blue, burnt sienna, raw umber, and ivory black you can mix virtually any color you will encounter in a master study. this palette covers warm and cool versions of each primary, two versatile earth tones, and a chromatic neutral. vermeer, titian, and velazquez all worked with palettes of similar scope.

“give me mud and i will paint the skin of venus, if you will let me surround it as i please.” — attributed to eugene delacroix

transparency matters. some pigments are naturally transparent (alizarin crimson, raw umber, ultramarine blue), some are opaque (titanium white, cadmium yellow, cadmium red). understanding this distinction is critical for glazing — you cannot glaze with opaque paint. most paint tubes are labeled with a transparency indicator; learn to read it.

brushes & palette knives

the brush is where intention meets canvas. there are hundreds of brush types, but for classical oil painting you need only two categories: stiff hog bristle brushes for blocking in and opaque passages, and soft sable or synthetic brushes for blending and detail.

hog bristle flats: these are your workhorses. the stiff bristles push thick paint around and leave a characteristic textured stroke. buy sizes 4, 6, 8, and 10 in flats. flats give you both broad coverage (using the flat of the brush) and sharp lines (using the edge). long flats are more versatile than short flats (sometimes called brights) for beginners.

soft rounds: sable is the traditional choice, but modern synthetics like da vinci nova or winsor & newton monarch work well and are more affordable. use these for detail work, fine lines, and blending. sizes 2 and 4 are sufficient to start.

filberts: a filbert is a flat brush with a rounded tip. many painters find it the most versatile shape because it can lay in broad strokes and also turn to produce soft, rounded marks. if you want to add one more brush shape, add a filbert in size 6 or 8.

palette knives: you need at least one for mixing paint on the palette. a trowel-shaped knife with a 3-4 inch blade and an offset handle is standard. palette knives are also painting tools — used for scraping, impasto application, and creating textured effects — but for now, focus on using yours for mixing.

care: clean brushes thoroughly after every session. rinse in odorless mineral spirits, wipe, then wash with brush soap or mild dish soap and warm water. reshape the bristles and store upright in a jar. a neglected brush is a dead brush.

surfaces & preparation

oil paint can be applied to any surface that has been properly primed — canvas, linen, wood panel, paper, even metal. the primer creates a barrier between the oil paint and the support, preventing the oil from rotting organic fibers and providing a surface with the right amount of tooth (texture) for the paint to grip.

canvas vs. panel: stretched canvas is the most common support. it is lightweight and has a pleasant spring under the brush. canvas panels (canvas glued to cardboard or mdf) are cheaper and excellent for studies. rigid panels — mdf, birch plywood, or hardboard — are preferred by many classical painters because they are completely smooth and do not flex. vermeer, van eyck, and most of the flemish and dutch masters painted on wood panels.

gesso: acrylic gesso is the standard modern primer. it is water-based, dries quickly, and provides good tooth. apply two to three thin coats, sanding lightly between coats with 220-grit sandpaper. for a smoother surface (ideal for detailed classical work), apply more coats and sand more. for a rougher surface (better for expressive brushwork), fewer coats are sufficient.

traditional gesso: cennini described true gesso — rabbit skin glue mixed with chalk (calcium carbonate) — in il libro dell'arte. this produces a brilliant white, absorbent ground that is beautiful to paint on but more fragile than acrylic gesso and cannot be used on flexible canvas. if you are painting on rigid panels and want the full classical experience, traditional gesso is worth trying later in your practice.

toned grounds: many old masters did not paint on white. they toned their grounds with a thin, transparent layer of earth color — raw umber, burnt sienna, or a warm gray — thinned with solvent. this eliminates the intimidation of a blank white surface and provides a useful middle value against which to judge both lights and darks. velazquez worked on warm reddish grounds. the venetians preferred warm umber tones. try a thin wash of raw umber or burnt sienna over your white gesso and let it dry before beginning.

sizing: if you are working on raw canvas or linen (without gesso), you must first seal it with sizing — traditionally rabbit skin glue, now often replaced by pva size or a coat of acrylic medium. this prevents oil from reaching the fibers. pre-primed canvases from art stores already have this step done.

mediums explained

a medium is anything you add to paint to change its handling properties. mediums can make paint thinner, thicker, faster-drying, slower-drying, more transparent, or glossier. understanding mediums is essential for the layered approach because you need to control how fat (oil-rich) each layer is.

the fat over lean rule: this is the single most important technical rule in oil painting. each successive layer must contain at least as much oil as the layer beneath it. if you paint a fat (oil-rich) layer under a lean (solvent-heavy) layer, the lean layer will dry first and crack as the fat layer beneath it continues to shrink. think of it as building on a stable foundation.

odorless mineral spirits (oms): used to thin paint in the early stages. oms evaporates and leaves behind only pigment and a small amount of oil, creating a lean layer. gamsol is the most commonly recommended brand. never use turpentine if you are sensitive to fumes — oms is much safer. use in a well-ventilated space.

linseed oil: the most common drying oil. refined linseed oil is the standard. it slows drying slightly, increases flow and gloss, and makes the paint film more flexible. cold-pressed linseed oil dries faster and has more body. stand oil is linseed oil that has been heated — it is thick, leveling, and excellent for glazing mediums because it yellows less than regular linseed oil.

walnut oil: yellows less than linseed oil and was preferred by leonardo da vinci. it dries more slowly and produces a slightly less durable film. a good choice for whites and light colors where yellowing would be most noticeable.

damar varnish: a natural tree resin dissolved in turpentine. it adds gloss, body, and speeds drying slightly. mixed with linseed oil and turpentine/oms, it creates a traditional glazing medium. the classic recipe is one part damar varnish, one part stand oil, and one part oms.

liquin: gamblin's alkyd-based medium. it speeds drying time significantly (touch-dry overnight) and gives the paint a smooth, enamel-like quality. many contemporary classical painters use it as a convenience medium for the layered approach because it allows you to paint a new layer the next day instead of waiting several days for linseed oil layers to dry.

practical approach for beginners: start with just two mediums — oms for thinning in the early layers, and a mixture of one part linseed oil to one part oms for later layers. as your layers progress toward the finish, increase the proportion of oil. this naturally satisfies the fat-over-lean rule without overthinking it.

underpainting

the underpainting is the foundation of a classical oil painting. it establishes the composition, proportions, and value structure before any color is applied. think of it as the skeleton of the painting — everything that follows depends on getting this stage right.

drawing the composition: begin by sketching the composition onto your toned ground using vine charcoal or a thin brush loaded with raw umber thinned heavily with oms. focus on placement, proportions, and the big shapes. do not draw details. blow off excess charcoal dust before painting over it — loose charcoal particles will muddy your paint.

if you need to strengthen your drawing skills before tackling underpainting, work through our how to draw guide first. accurate drawing is the bedrock of classical painting.

grisaille: the most traditional underpainting approach is the grisaille — a monochrome painting in gray tones using black and white. the grisaille establishes every value relationship in the painting. if the grisaille reads well, the color layers built on top of it will read well. rubens, van dyck, and many flemish painters used grisaille underpaintings.

brunaille: a variation of grisaille using warm earth tones — raw umber, burnt umber, or burnt sienna with white — instead of black and white. many painters prefer this because warm underpaintings create a natural glow when cool colors are glazed over them. rembrandt's underpaintings were typically brunaille — warm earth tones that show through the final layers and unify the painting.

verdaccio: a green-gray underpainting, traditional in italian fresco and tempera painting. cennini describes it in detail. the green undertone counteracts the warmth of skin tones painted over it, producing a natural, lifelike complexion. if you are painting figures, verdaccio is worth exploring.

technique: thin your underpainting color heavily with oms — you want a wash-like consistency, almost like watercolor. this creates the leanest possible layer, which is exactly what the fat-over-lean rule demands at this stage. paint the darkest darks first, then lift out lights by wiping with a rag or adding a small amount of white. work in broad masses. keep edges soft. the entire underpainting should take one session and be dry within a day or two.

“drawing is the probity of art.” — jean-auguste-dominique ingres

dead coloring

dead coloring (sometimes called the dead layer or first painting) is the stage between underpainting and the finished surface. it is where you establish the local colors of the painting — the actual hues of objects as they appear in flat, diffused light, without the effects of strong light and shadow.

the term “dead” refers to the deliberately muted, chalky quality of this layer. you mix your colors slightly lighter and less saturated than the final intended colors. this is intentional: the glaze layers that follow will deepen values and intensify color. if you paint the dead layer at full saturation, the glazes will push everything too dark.

approach: mix your local colors on the palette first. use a medium of roughly two parts oms to one part linseed oil — a bit fatter than the underpainting but still relatively lean. paint with opaque or semi-opaque color, covering the underpainting but allowing its value structure to guide you. work in broad areas. keep edges soft where forms turn and sharp where forms meet.

eastlake noted that the venetian painters — titian, giorgione, veronese — were masters of dead coloring. they would establish a complete, if muted, version of the painting in opaque color before applying a single glaze. the dead layer does the heavy lifting; the glazes do the magic.

temperature shifts: this is a good stage to think about warm and cool color temperature. shadows tend to be warm and lights tend to be cool in indoor lighting (and the reverse in outdoor lighting). paint these temperature shifts into your dead layer. even though the color is muted, the temperature relationships should be correct. for a thorough treatment of color temperature, see color theory for painters.

drying: let the dead layer dry completely before proceeding to glazing. depending on your medium and paint thickness, this can take anywhere from two days to a week. the surface should be dry to the touch and not tacky.

glazing

glazing is the technique that gives classical oil painting its extraordinary luminosity. a glaze is a thin, transparent layer of paint — almost pure pigment suspended in medium, with no white added — applied over a dry layer beneath. light passes through the transparent glaze, reflects off the opaque layer below, and passes back through the glaze again. this creates a depth and richness of color that is impossible to achieve by mixing paint on the palette.

this is the same principle as stained glass. the “glow” you see in vermeer's paintings, in van eyck's jewel-like surfaces, and in titian's rich flesh tones comes from glazing over carefully prepared opaque layers. for a complete deep dive, read our glazing technique in oil painting guide.

which pigments to glaze with: only naturally transparent or semi-transparent pigments produce true glazes. the best glazing pigments include:

• alizarin crimson (deep, cool red)
• ultramarine blue (warm blue, excellent for shadows)
• raw umber and burnt sienna (warm earth glazes)
• viridian (cool, transparent green)
• indian yellow or transparent yellow oxide
• transparent red oxide (warm, rich red-brown)

glazing medium: mix your glazing medium from one part stand oil, one part damar varnish, and one part oms. alternatively, use liquin thinned slightly with oms. the medium should make the paint flow smoothly and dry to a glass-like film. apply with a soft brush — a large soft flat or a badger blender — in thin, even coats.

building depth: multiple thin glazes produce more depth than a single thick one. you might glaze a shadow area with raw umber, let it dry, then glaze again with ultramarine blue to cool and deepen it. each glaze subtly shifts the color and value. vermeer was particularly masterful at this — his blue headscarf in girl with a pearl earring was built from multiple glazes of ultramarine and natural ultramarine (lapis lazuli) over a dark underpainting. to learn more about his specific methods, see paint like vermeer.

“the great painters gave transparency to their shadows and were very sparing of it in their lights.” — charles lock eastlake, methods and materials of painting

scumbling: the opposite of glazing. a scumble is a thin, opaque or semi-opaque layer dragged lightly over a dry surface so that the layer beneath shows through the texture. it is useful for creating atmospheric effects, softening edges, and cooling warm passages. where glazing deepens and warms, scumbling lightens and cools. the old masters used both in combination.

oiling out: after a painting has dried, some passages may appear matte and “sunken in” while others remain glossy. before applying glazes, you need a uniform surface. oiling out means rubbing a very thin coat of medium (linseed oil or your glazing medium thinned with oms) over the dry surface with a lint-free cloth, then wiping off the excess. this restores the sunken areas to their true value and provides a wet surface for the glaze to bond to.

impasto

impasto is the application of thick, undiluted paint so that brush strokes and palette knife marks remain visible on the surface. it is the physical opposite of glazing — where glazing is thin and transparent, impasto is thick and opaque. but the two techniques are not mutually exclusive. in fact, the most powerful classical paintings combine both: thick impasto in the lights, thin transparent glazes in the shadows.

rembrandt is the great master of impasto. in his late self-portraits, the flesh of the face is built up in thick ridges of paint that catch real light and create an almost sculptural presence. the jeweled chain in the man with the golden helmet (now attributed to his workshop) is pure impasto — thick strokes of yellow and white that physically project from the canvas. yet the shadows in these same paintings are thin, transparent, and warm. this contrast between thick lights and thin shadows is one of the hallmarks of great oil painting. explore his full technique in our paint like rembrandt guide.

when to use impasto: reserve thick paint for the areas of greatest light, highest texture, and strongest visual interest. highlights on skin, the sparkle of metal or glass, the thick folds of fabric in light — these are natural candidates. impasto draws the eye because it literally catches light in the room. use it strategically.

technique: load your brush or palette knife with undiluted paint — no medium, no solvent. apply it with confidence in a single stroke and resist the urge to fuss. the power of impasto comes from bold, decisive marks. if you overwork it, you lose the freshness and the paint turns muddy.

fat-over-lean: impasto is the fattest layer in a classical painting because it is pure paint (pigment and oil) with no solvent. this means it belongs in the final stages, applied over leaner layers. never apply thick impasto directly on a lean underpainting — the impasto will crack.

white impasto: the old masters often applied thick white impasto in highlight areas during the opaque painting stage, then glazed transparent color over it. the glaze tints the white impasto while preserving its three-dimensional texture. this produces intensely luminous highlights — the technique behind vermeer's bread crusts, rembrandt's jewelry, and van eyck's metalwork.

alla prima vs layered approach

everything we have discussed so far is part of the layered approach: underpainting, dead coloring, glazing, impasto highlights — each stage done over dry layers. but there is another major approach to oil painting: alla prima, italian for “at the first attempt.”

alla prima (direct painting): the painting is completed in one session (or a few sessions) while the paint is still wet. there is no underpainting, no dead layer, no glazing. you mix your final color and value on the palette and apply it directly to the canvas, blending wet-into-wet. the impressionists — monet, renoir, pissarro — were primarily alla prima painters. so were john singer sargent, joaquin sorolla, and anders zorn.

advantages of alla prima: spontaneity, freshness, speed. because you are working wet-into-wet, you can achieve incredibly smooth blends and soft edges. the finished painting retains the energy and immediacy of the painting process. alla prima is ideal for plein air painting, quick studies, and any subject that demands speed (live models, changing light).

advantages of the layered method: control, depth, luminosity. the layered approach lets you solve problems one at a time. transparent glazes produce optical color effects that direct mixing cannot achieve. you can rework any stage without disturbing what is underneath. the layered method is ideal for complex compositions, detailed subjects, and any painting where you want the deep, glowing color that characterizes the old masters.

the reality: most painters use a combination. you might do a layered underpainting, then finish passages alla prima on top. or you might paint mostly alla prima but add glazes at the end. harold speed argued that the best painting combines both approaches — using the layered method for its structural advantages and direct painting for its vitality. sargent did exactly this: his portraits have bold alla prima brushwork in the flesh, but he often scumbled and glazed the backgrounds.

as a beginner, learn both. start with the layered approach because it is more forgiving and teaches you to think in stages. once you are comfortable with your materials, try alla prima studies. eventually, you will develop a personal method that draws from both traditions.

the best way to learn oil painting is to paint. but informed practice beats uninformed practice every time. these books will deepen your understanding of the classical method:

• harold speed — oil painting techniques and materials (1924). the most practical and clearly written book on classical oil painting. speed covers composition, drawing, tone, color, and technique with a focus on how the old masters actually worked.
• charles lock eastlake — methods and materials of painting of the great schools and masters (1847). a scholarly but readable account of how the flemish, venetian, and spanish schools prepared their materials and built their paintings. essential for understanding historical practice.
• cennino cennini — il libro dell'arte (the craftsman's handbook) (c. 1390). the oldest surviving european painting manual. cennini describes tempera technique in detail, and much of his advice on drawing, preparation, and layering carries directly into oil painting.
• ralph mayer — the artist's handbook of materials and techniques (1940, revised editions). the definitive reference on painting materials. dense but invaluable for understanding what your materials are and how they behave.
• virgil elliott — traditional oil painting: advanced techniques and concepts from the renaissance to the present. a modern treatment that bridges historical methods and contemporary practice. excellent chapter on glazing and optical effects.

start with speed. his writing is direct, opinionated, and practical. when you want to go deeper into the historical methods, move to eastlake and cennini. mayer and elliott are references to consult as questions arise.

if you are starting from scratch and want to build your drawing foundation before picking up a brush, begin with our how to draw guide. if you are ready to study specific masters, explore the paint like vermeer and paint like rembrandt guides to see the classical method applied to specific artists.

the classical method rewards patience. each painting you complete teaches you something the last one did not. the materials become familiar, the process becomes intuitive, and the gap between what you see in your mind and what appears on the canvas narrows. that is the promise of deliberate practice — and it is why the old masters were masters.
