John Crome is high-key - luminous, open, and weighted toward light. John Crome builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #D5D1BE at 25.1% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. Only 5.8% is devoted to #593922, yet that small allocation delivers the palette's entire chromatic tension. 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 3 of John Crome's sequence - a single chapter in a chromatic story told across many works.
