The value structure of John Riley is mid-key: quiet, controlled, and cohesive. Warmth dominates - the palette of John Riley leans heavily on the yellow-orange-red arc of the colour wheel. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #815839 - appears at just 4.4%, deployed as a precision accent against the quieter ground. The full value range is 67 units: broad enough to build convincing three-dimensional form. This is palette 2 of John Riley's sequence - a single chapter in a chromatic story told across many works.
