Light floods Purism; the palette keeps values pale and airy across its range. The palette tilts toward cool - blues and silver-greys carry the structural weight. Saturation is measured and controlled, giving the palette presence without visual aggression. The most saturated colour, #D4D06D, covers 47.1% of the surface: too much to call an accent, too strong to ignore. 40 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
