Japonism distributes its values across the middle register, creating harmony without high contrast. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #674733 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.9%). Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity.
