Art Brut distributes its values across the middle register, creating harmony without high contrast. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The palette gives 29.0% of the composition to a single #1F1D20 - a decisive chromatic anchor. The saturated accent, #A88435, registers at 1.4% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 65 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
