Synthetic Cubism is strongly light-biased - shadow is suggested rather than declared. The palette tilts toward cool - blues and silver-greys carry the structural weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 2.9% is devoted to #835B27, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 77 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
