Sanyu is high-key - luminous, open, and weighted toward light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. A single dominant - #E3D8BE at 39.5% - sets the character of the whole composition. At 2.8%, #AE5F5C carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range of 53 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Sanyu's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
