The value structure of William Hawkins is mid-key: quiet, controlled, and cohesive. 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. #0B0E0D claims 38.5% of the surface, functioning as the work's tonal foundation. Only 1.7% is devoted to #A52F19, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 81 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of William Hawkins's sequence - a single chapter in a chromatic story told across many works.
