The value structure of Robert Spencer is mid-key: quiet, controlled, and cohesive. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #595126 - appears at just 5.6%, deployed as a precision accent against the quieter ground. The full value range is 58 units: broad enough to build convincing three-dimensional form. This is palette 6 of Robert Spencer's sequence - a single chapter in a chromatic story told across many works.
