Richard Gerstl sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The chromatic peak belongs to #2C152B, and at 9.7% it dominates, not decorates. 71 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 Richard Gerstl's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
