The value structure of Henry Ossawa Tanner is mid-key: quiet, controlled, and cohesive. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #505117 - appears at just 4.1%, deployed as a precision accent against the quieter ground. A value spread of 70 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Henry Ossawa Tanner's palette 5 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
