Theo van Doesburg distributes its values across the middle register, creating harmony without high contrast. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #414C20 delivers the chromatic peak at only 10.8% - a small shot of colour with outsized visual impact. The palette spans 54 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 10 sits within the larger chromatic argument that Theo van Doesburg's complete body of work advances.
