Art Brut occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Built 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 dominant colour, #C0B096, takes 31.6% of the total area, establishing the overall mood before any other hue is introduced. At 4.0%, #78252E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 58 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
