The value structure of Henry Moore is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #54719D functions as the palette's exclamation mark: highest chroma, lowest percentage (9.1%). At 54 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. Henry Moore's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
