The value structure of Frederick McCubbin is mid-key: quiet, controlled, and cohesive. Frederick McCubbin 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. The most saturated colour, #4A372B, is reserved to 7.2% of the surface, where it acts as a focal punctuation. Value range is moderate at 43 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 6 sits within the larger chromatic argument that Frederick McCubbin's complete body of work advances.
