Low-key values are the structural spine of Tenebrism, giving it gravity and atmosphere. The palette orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #242323 claims 72.3% of the surface, functioning as the work's tonal foundation. The saturated accent, #BD8D6E, registers at 3.4% - sparse enough to feel like a deliberate surprise. The value range spans 58 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Together these qualities place the palette firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display.
