Values in Diego Rivera rest in the mid-range - neither dramatically lit nor steeped in shadow. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 12.7%, #7B4A2E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 69 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 3 of Diego Rivera's sequence - a single chapter in a chromatic story told across many works.
