Mid-key values give James Webb its characteristic quietness - nothing blazes, nothing disappears. James Webb 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. #9E7944 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.9%). The full value range is 56 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 12 sits within the larger chromatic argument that James Webb's complete body of work advances.
