William Leighton Leitch sits in the centre of the value range, lending the palette a sense of even, sustained light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #986B22 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.7%). The value range spans 60 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. The palette is a signature: William Leighton Leitch's particular sense of value, warmth, and colour weight made legible.
