Light floods John Leech; the palette keeps values pale and airy across its range. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #C75A39 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.2%). A value spread of 74 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of John Leech's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
