The value structure of Art Deco is mid-key: quiet, controlled, and cohesive. Warmth dominates - the palette leans heavily on the yellow-orange-red arc of the colour wheel. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #864841, is reserved to 4.7% of the surface, where it acts as a focal punctuation. At 61 units of value range, the palette has the tonal breadth to sustain complex spatial readings.
