recreation guide

This recreation guide focuses on the technical execution of a Rococo-style oil portrait by Lemuel Francis Abbott, specifically 'Portrait of Valentine Green.' While the specific visual details of this particular painting (such as the sitter's pose or clothing) are not described in the provided sources, the guide relies on the documented practices of the period and the general principles of oil painting relevant to Abbott's era. The process emphasizes the traditional 'old master' technique of building a monochrome underpainting (grisaille) before applying transparent color layers, a method cited by Sir Joshua Reynolds and consistent with the Rococo emphasis on luminosity and finish. The guide also incorporates the laws of simultaneous color contrast to ensure the flesh tones and background harmonize correctly, avoiding the flatness that can result from ignoring optical interactions between adjacent hues.

estimated time

40-60 hours over 6-8 weeks (allowing for drying times between glaze layers)

Varnish	Mixed with oil for later glazing stages to increase transparency and flow	Dammar varnish or synthetic resin varnish
Solvents (Mineral Spirits/Turpentine)	Thinning paint and cleaning brushes	Odorless mineral spirits

preparation

surface prep

The surface should be prepared to accept oil paint. While specific priming methods for Abbott are not detailed in the sources, traditional oil painting techniques of the period involved preparing a ground that allows for the 'fat over lean' rule, ensuring each subsequent layer contains more oil than the previous one to prevent cracking (Source 5).

underdrawing

Begin by sketching the subject onto the canvas using charcoal or thinned paint (Source 5). This initial drawing establishes the likeness and composition. Since the goal is a portrait, the drawing must capture the 'inner essence' and character of the sitter, focusing on the eyes and eyebrows to convey expression, as the mouth is likely to remain neutral or serious (Source 4).

underpainting

Execute a monochrome underpainting (grisaille) using black, ultramarine, and white mixed with oil of copavia or linseed oil (Source 1). This step involves mentally extracting red and yellow colors to establish the tonal structure of the painting (Source 1). This grisaille serves as the foundation for the subsequent color layers.

composition

The composition should aim for a 'three-quarter view' or 'half-length' depiction, which is common in portrait painting to show character and moral quality rather than just literal likeness (Source 4). The arrangement should consider the law of simultaneous contrast, ensuring that the colors of the draperies and background harmonize with the inherent colors of the flesh, eyes, and hair (Source 2).

step by step

underdrawing→underpainting→first pass→drying→refining→finishing

underdrawing

step 01
Sketch the subject's likeness using charcoal or thinned paint, focusing on the eyes and eyebrows to capture character.
Tip — Ensure the proportions are accurate, as the underpainting will rely on this structure.
Initial Sketch

underpainting

step 02
Paint the entire composition in monochrome using black, ultramarine, and white mixed with oil of copavia. Establish the chiaroscuro and tonal values.
Tip — Mentally extract red and yellow colors to focus on the underlying structure.
Grisaille

first pass

step 04
Apply transparent glazes of red and yellow tones over the dry grisaille using oil as a medium. This mimics tinting an engraving with watercolors.
Tip — Use thin, transparent layers to allow the underlying monochrome to show through.
Glazing

drying

step 03
Allow the grisaille to dry completely before proceeding to color layers.
Tip — Oil paint dries by oxidation, usually taking two weeks to be dry to the touch.
Drying

refining

step 05
Use scumbling (semi-opaque painting) to adjust tones, particularly over darker grounds to create coldness or grey blooms if needed.
Tip — Ensure the underlying painting makes itself felt through the semi-opaque layer.
Scumbling
step 06
Adjust colors based on the law of simultaneous contrast, ensuring that adjacent colors do not appear distorted by their complements.
Tip — Check that the lightest tones are not lowered and darkest tones are not heightened incorrectly due to juxtaposition.
Simultaneous Contrast

finishing

step 07
Apply final glazes with a mixture of varnish and oil for greater mastery and depth, if desired.
Tip — This step requires sufficient mastery to avoid muddying the colors.
Varnish Glazing

critical techniques

Glazing

Applying a transparent coat of color over a dry underpainting to build up luminosity and depth, as practiced by old masters and cited by Reynolds.

Scumbling

Using semi-opaque paint over a darker ground to create coldness or grey blooms, allowing the underlying layer to influence the final appearance.

Simultaneous Contrast

Adjusting colors based on their interaction with adjacent hues to ensure accurate perception and harmony, particularly for flesh tones against draperies.

common pitfalls

→Applying layers with less oil than the previous layer, violating the 'fat over lean' rule, which can lead to cracking and peeling (Source 5).
→Ignoring the law of simultaneous contrast, resulting in colors that appear distorted or disharmonious due to juxtaposition (Source 2).
→Attempting to glaze before the underpainting is completely dry, which can muddy the colors and ruin the transparency (Source 1).
→Focusing too much on literal likeness rather than capturing the inner character and moral quality of the sitter (Source 4).
