John Martin distributes its values across the middle register, creating harmony without high contrast. Warmth dominates - the palette of John Martin leans heavily on the yellow-orange-red arc of the colour wheel. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #52402F functions as the palette's exclamation mark: highest chroma, lowest percentage (10.1%). 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Palette 1 sits within the larger chromatic argument that John Martin's complete body of work advances.
