The high-key values of William Leighton Leitch give it an effulgent, almost bleached quality. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #B78D72 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.6%). The value range of 49 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 1 sits within the larger chromatic argument that William Leighton Leitch's complete body of work advances.
