Values in Edouard Riou rest in the mid-range - neither dramatically lit nor steeped in shadow. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #C7C4A3, is reserved to 8.0% of the surface, where it acts as a focal punctuation. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. In the context of Edouard Riou's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
