Umberto Boccioni is high-key - luminous, open, and weighted toward light. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 46.0%, #FAFAFB functions less as a colour accent and more as a complete atmospheric environment. The saturated accent, #BB8963, registers at 3.1% - sparse enough to feel like a deliberate surprise. A value spread of 83 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 9 sits within the larger chromatic argument that Umberto Boccioni's complete body of work advances.
