Penry Williams is high in key: pale, luminous, and filled with optical air. 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. The most saturated colour, #8B7041, is reserved to 9.3% of the surface, where it acts as a focal punctuation. 61 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Penry Williams's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
