The palette of John Riley sits in the lower register of the value scale - dense, contained, and weighted. John Riley builds on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. At 2.5%, #9B735A carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 57 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Together these qualities place John Riley firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Palette 9 sits within the larger chromatic argument that John Riley's complete body of work advances.
