Diego Rivera occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm hues command this palette; Diego Rivera favours the reds, oranges, and yellows of firelight and earth. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. Only 2.0% is devoted to #A7376D, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 62 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This is palette 1 of Diego Rivera's sequence - a single chapter in a chromatic story told across many works.
