The high-key values of Katsushika Hokusai give it an effulgent, almost bleached quality. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #997551, registers at 8.6% - sparse enough to feel like a deliberate surprise. A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Katsushika Hokusai's palette 9 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
