Low-key values are the structural spine of Rococo, giving it gravity and atmosphere. Temperature reads distinctly warm: the reds and earth tones carry the compositional weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. 31.5% of the palette belongs to #292625, a concentration that makes it the unmistakable visual centre. #B5865D delivers the chromatic peak at only 3.4% - a small shot of colour with outsized visual impact. The value range spans 61 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This tonal restraint is characteristic of the Tonalist sensibility: colour serves light, not the reverse.
