Penry Williams occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. At 5.6%, #81463B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 50 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 5 of Penry Williams's sequence - a single chapter in a chromatic story told across many works.
