Pieter de Hooch is low-key throughout, a quality associated with Nocturnal Terracotta - deep shadows dominate the composition. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The most saturated colour, #6E260C, is reserved to 6.9% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. Pieter de Hooch follows the old-master formula: deep values, warm underlighting, and chroma held in reserve for the focal point. In the context of Pieter de Hooch's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
