Robert Henri is low-key throughout, a quality associated with Nocturnal Cinder - deep shadows dominate the composition. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. The dominant colour, #111116, takes 34.9% of the total area, establishing the overall mood before any other hue is introduced. The most saturated colour, #D5C497, is reserved to 3.0% of the surface, where it acts as a focal punctuation. At 76 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This tonal restraint is characteristic of the Robert Henri approach: colour serves light, not the reverse. This is palette 10 of Robert Henri's sequence - a single chapter in a chromatic story told across many works.
