Abstract Expressionism is strongly light-biased - shadow is suggested rather than declared. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #C6A345, registers at 4.2% - sparse enough to feel like a deliberate surprise. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
