Tonalism sits in the centre of the value range, lending the palette a sense of even, sustained light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. #9D813E delivers the chromatic peak at only 8.7% - a small shot of colour with outsized visual impact. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
