The value structure of John Pettie is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #705126, is reserved to 8.1% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 66 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. John Pettie's palette 7 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
