The palette of Rembrandt sits in the lower register of the value scale - dense, contained, and weighted. Warmth dominates - the palette of Rembrandt leans heavily on the yellow-orange-red arc of the colour wheel. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. 36.9% of the palette belongs to #140C0C, a concentration that makes it the unmistakable visual centre. The saturated accent, #8B2711, registers at 1.5% - sparse enough to feel like a deliberate surprise. The full value range is 63 units: broad enough to build convincing three-dimensional form. This tonal restraint is characteristic of the Rembrandt approach: colour serves light, not the reverse. In the context of Rembrandt's full range of palettes, group 15 represents one movement in an ongoing chromatic dialogue.
