Mid-key values give Art Informel its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. #CC6D37 delivers the chromatic peak at only 3.2% - a small shot of colour with outsized visual impact. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
