Edouard Riou occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #DBD4C3, is reserved to 12.0% of the surface, where it acts as a focal punctuation. At 62 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette is a signature: Edouard Riou's particular sense of value, warmth, and colour weight made legible.
