Cubo-Futurism as a style is partly defined by its colour: this palette makes that definition concrete. Cubo-Futurism distributes its values across the middle register, creating harmony without high contrast. Built on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 5.7% is devoted to #CD8D51, yet that small allocation delivers the palette's entire chromatic tension. 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Applied to contemporary work, these proportions immediately evoke the Cubo-Futurism register.
