The value structure of Edward Henry Holder is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #423A1C, is reserved to 5.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 67 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Edward Henry Holder preferred, made measurable.
