The value structure of Ralph Blakelock 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 highest-chroma note - #827A48 - appears at just 2.8%, deployed as a precision accent against the quieter ground. At 38 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 7 sits within the larger chromatic argument that Ralph Blakelock's complete body of work advances.
