The high-key values of Cubo-Futurism give it an effulgent, almost bleached quality. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The saturated accent, #B24029, registers at 3.0% - sparse enough to feel like a deliberate surprise. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
