Cubism keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 3.4% is devoted to #38456A, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 68 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.
