Arthur Hacker distributes its values across the middle register, creating harmony without high contrast. Yellow, ochre, sienna: warm hues that Arthur Hacker deploys as the palette's primary energy. All colours lean toward grey, building depth through value rather than colour punch. At 3.3%, #9F432B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 77 units: broad enough to build convincing three-dimensional form. This is palette 3 of Arthur Hacker's sequence - a single chapter in a chromatic story told across many works.
