Diego Rivera occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #4D431C, registers at 8.1% - sparse enough to feel like a deliberate surprise. Value range is moderate at 52 units - enough contrast for legibility, not so much as to fragment the tonal unity. In the context of Diego Rivera's full range of palettes, group 7 represents one movement in an ongoing chromatic dialogue.
