Katsushika Hokusai distributes its values across the middle register, creating harmony without high contrast. 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, #DD9741, is reserved to 2.5% of the surface, where it acts as a focal punctuation. 67 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Katsushika Hokusai's full range of palettes, group 12 represents one movement in an ongoing chromatic dialogue.
