Alexander Koester distributes its values across the middle register, creating harmony without high contrast. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. #D2D0BA delivers the chromatic peak at only 8.4% - a small shot of colour with outsized visual impact. The value range spans 64 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 Alexander Koester's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
