Henry Ossawa Tanner occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Henry Ossawa Tanner builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 6.4%, #6E5931 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 3 of Henry Ossawa Tanner's sequence - a single chapter in a chromatic story told across many works.
