Values in Sanyu tilt decisively toward white, giving the palette its luminous character. Temperature reads distinctly warm: the reds and earth tones from Sanyu carry the compositional weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #E2D8CB at 33.9% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #BC5E47 delivers the chromatic peak at only 0.5% - a small shot of colour with outsized visual impact. A value spread of 79 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 4 sits within the larger chromatic argument that Sanyu's complete body of work advances.
