Tenebrism is built on dark foundations, with values clustered toward shadow. Warmth dominates - the palette leans heavily on the yellow-orange-red arc of the colour wheel. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The dominant colour, #1C181B, takes 32.8% of the total area, establishing the overall mood before any other hue is introduced. The saturated accent, #D3894C, registers at 1.2% - sparse enough to feel like a deliberate surprise. A value spread of 60 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.
