Light floods Constructivism; the palette keeps values pale and airy across its range. 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. The highest-chroma note - #407CA4 - appears at just 0.5%, deployed as a precision accent against the quieter ground. The full value range is 61 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
