The value structure of Charles D'Oyly is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #B49461 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.8%). From deepest dark to palest light, the palette traverses 72 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Charles D'Oyly's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
