Expressionism is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #2F597F delivers the chromatic peak at only 2.2% - a small shot of colour with outsized visual impact. 70 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
