The value structure of Edward Collier is mid-key: quiet, controlled, and cohesive. Yellow, ochre, sienna: warm hues that Edward Collier deploys as the palette's primary energy. All colours lean toward grey, building depth through value rather than colour punch. #301E15 delivers the chromatic peak at only 13.0% - a small shot of colour with outsized visual impact. Value range is moderate at 42 units - enough contrast for legibility, not so much as to fragment the tonal unity. Palette 4 sits within the larger chromatic argument that Edward Collier's complete body of work advances.
