François Gérard is low-key throughout, a quality associated with Tenebrous Sienna - deep shadows dominate the composition. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The dominant colour, #161513, takes 47.8% of the total area, establishing the overall mood before any other hue is introduced. The most saturated colour, #E1AF75, is reserved to 1.2% of the surface, where it acts as a focal punctuation. A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This tonal restraint is characteristic of the François Gérard approach: colour serves light, not the reverse. This is palette 8 of François Gérard's sequence - a single chapter in a chromatic story told across many works.
