William Leighton Leitch is strongly light-biased - shadow is suggested rather than declared. William Leighton Leitch builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The dominant colour, #D0D5D1, takes 30.1% of the total area, establishing the overall mood before any other hue is introduced. The saturated accent, #6981A7, registers at 4.1% - sparse enough to feel like a deliberate surprise. Value range is moderate at 46 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 2 of William Leighton Leitch's sequence - a single chapter in a chromatic story told across many works.
