Across the abstract movement, certain palette qualities recur - this distillation makes them visible at a glance. The value structure of abstract is mid-key: quiet, controlled, and cohesive. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #DFBA3E, registers at 2.0% - sparse enough to feel like a deliberate surprise. At 62 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is the light that abstract painters chose to live inside.
