Yasuo Kuniyoshi 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. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #553E30, is reserved to 8.9% of the surface, where it acts as a focal punctuation. The palette spans 52 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 4 of Yasuo Kuniyoshi's sequence - a single chapter in a chromatic story told across many works.
