The value structure of Wilhelm Kotarbinski is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #2B3A59 delivers the chromatic peak at only 1.4% - a small shot of colour with outsized visual impact. The value range spans 72 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Wilhelm Kotarbinski's full range of palettes, group 7 represents one movement in an ongoing chromatic dialogue.
