The value structure of William Henry Mander is mid-key: quiet, controlled, and cohesive. William Henry Mander builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 4.8%, #E6E1D1 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 74 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that William Henry Mander's complete body of work advances.
