Eric Ravilious 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, #AD986E, is reserved to 4.6% of the surface, where it acts as a focal punctuation. At 56 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Eric Ravilious's complete body of work advances.
