Arthur Hacker distributes its values across the middle register, creating harmony without high contrast. Temperature reads distinctly warm: the reds and earth tones from Arthur Hacker carry the compositional weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. 26.3% of the palette belongs to #150F16, a concentration that makes it the unmistakable visual centre. The saturated accent, #9F5234, registers at 1.7% - sparse enough to feel like a deliberate surprise. At 69 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Palette 5 sits within the larger chromatic argument that Arthur Hacker's complete body of work advances.
