Pontoise, the Road to Gisors in Winter

surface prep

The canvas should be primed with a white or light-toned ground to allow for the full range of color values and to facilitate the perception of light modifications. Pissarro’s practice involved painting directly from nature, so the surface should be prepared to accept wet-on-wet techniques without excessive absorption (Source 7).

underdrawing

Pissarro likely used minimal underdrawing, focusing instead on capturing the overall impression and light conditions directly. His method involved working on all parts of the painting simultaneously, keeping everything going on an equal basis (Source 7).

underpainting

There is no specific evidence in the sources that Pissarro used a grisaille or monochrome underpainting for this work. His plein air practice suggests a direct approach, applying color immediately to capture the fleeting effects of winter light (Source 7).

Plein air painting

Painting outdoors to capture the direct effects of light and weather, as practiced by Pissarro under the influence of Corot (Source 7).

Simultaneous contrast

Using the principle that colors appear different when placed next to each other, ensuring that the painting reflects the true modifications of light (Source 1).

Color harmony

Creating pleasing contrasts and consonances through the use of complementary, analogous, or triadic color schemes (Source 2).
