Robert Zund distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #4E6828, is reserved to 5.4% of the surface, where it acts as a focal punctuation. 62 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Robert Zund's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
