Penry Williams sits in the centre of the value range, lending the palette a sense of even, sustained light. Yellow, ochre, sienna: warm hues that Penry Williams deploys as the palette's primary energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #8C6D3F, is reserved to 8.7% of the surface, where it acts as a focal punctuation. A value spread of 62 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of Penry Williams's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
