Low-key values are the structural spine of Tenebrism, giving it gravity and atmosphere. Temperature reads distinctly warm: the reds and earth tones carry the compositional weight. All colours lean toward grey, building depth through value rather than colour punch. 30.2% of the palette belongs to #251516, a concentration that makes it the unmistakable visual centre. Only 7.1% is devoted to #5E2819, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 62 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.
