Naturalism works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. 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 34.9%, #E7D5B0 functions less as a colour accent and more as a complete atmospheric environment. #5E572A delivers the chromatic peak at only 6.9% - a small shot of colour with outsized visual impact. The full value range is 76 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
