William Coulter keeps values measured and balanced, a hallmark of tonal restraint. William Coulter builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The dominant colour, #C2C6C1, takes 25.0% of the total area, establishing the overall mood before any other hue is introduced. The highest-chroma note - #71503B - appears at just 5.0%, deployed as a precision accent against the quieter ground. Value range is moderate at 54 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. William Coulter arrived at this balance through long practice; the palette carries the weight of that experience.
