The value structure of John Jackson is mid-key: quiet, controlled, and cohesive. John Jackson 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. At 4.5%, #B6A27F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 52 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that John Jackson's complete body of work advances.
