Light floods Post-Impressionism; the palette keeps values pale and airy across its range. Built on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 4.1%, #A26748 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 56 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
