Abstract Expressionism is high in key: pale, luminous, and filled with optical air. The palette balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 2.9% is devoted to #7C4A4C, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 62 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
