Low-key values are the structural spine of Tenebrism, giving it gravity and atmosphere. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 36.9%, #1B1718 functions less as a colour accent and more as a complete atmospheric environment. Only 2.4% is devoted to #E3C08B, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 68 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Together these qualities place the palette firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display.
