The value structure of Sanyu is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #C4AF4F, is reserved to 4.4% of the surface, where it acts as a focal punctuation. At 67 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Sanyu's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
