Cubism is strongly light-biased - shadow is suggested rather than declared. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #936446, is reserved to 3.6% of the surface, where it acts as a focal punctuation. The full value range is 58 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
