Henry Ossawa Tanner keeps values measured and balanced, a hallmark of tonal restraint. Henry Ossawa Tanner tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 28.6%, #191A1C functions less as a colour accent and more as a complete atmospheric environment. The saturated accent, #CEC372, registers at 2.1% - sparse enough to feel like a deliberate surprise. The full value range is 70 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Henry Ossawa Tanner's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
