William Morris occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Rather than a studied accent, #282535 takes 3.6% - a bold allocation that saturates the composition's atmosphere. Value range is moderate at 38 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 5 of William Morris's sequence - a single chapter in a chromatic story told across many works.
