Henry Ossawa Tanner occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #18181B at 28.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #C5A15B delivers the chromatic peak at only 2.4% - a small shot of colour with outsized visual impact. The full value range is 74 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Henry Ossawa Tanner's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
