James Thornhill sits in the centre of the value range, lending the palette a sense of even, sustained light. James Thornhill 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. Only 10.0% is devoted to #4E2F10, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 67 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Taken together, these qualities constitute James Thornhill's chromatic voice - distinctive enough to be read across an entire body of work.
