Katsushika Hokusai is high-key - luminous, open, and weighted toward light. Katsushika Hokusai builds on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 30.1%, #A4A197 functions less as a colour accent and more as a complete atmospheric environment. #BB9A77 delivers the chromatic peak at only 7.2% - a small shot of colour with outsized visual impact. 56 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 7 of Katsushika Hokusai's sequence - a single chapter in a chromatic story told across many works.
