Judith Leyster dwells firmly in the shadows, with no more than a whisper of light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. 29.9% of the palette belongs to #151112, a concentration that makes it the unmistakable visual centre. The saturated accent, #805929, registers at 3.2% - sparse enough to feel like a deliberate surprise. A value spread of 67 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Judith Leyster's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
