Robert Henri is low-key throughout, a quality associated with Abyssal Sienna - deep shadows dominate the composition. Warmth dominates - the palette of Robert Henri leans heavily on the yellow-orange-red arc of the colour wheel. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. 50.2% of the palette belongs to #161515, a concentration that makes it the unmistakable visual centre. The most saturated colour, #E38855, is reserved to 1.3% of the surface, where it acts as a focal punctuation. The full value range is 64 units: broad enough to build convincing three-dimensional form. This tonal restraint is characteristic of the Robert Henri approach: colour serves light, not the reverse. This is palette 18 of Robert Henri's sequence - a single chapter in a chromatic story told across many works.
