Purism works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. A single dominant - #EEE8DD at 61.3% - sets the character of the whole composition. The most saturated colour, #203462, is reserved to 1.5% of the surface, where it acts as a focal punctuation. At 70 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
