Mid-key values give Tenebrism its characteristic quietness - nothing blazes, nothing disappears. Yellow, ochre, sienna: warm hues deployed as the palette's primary energy. All colours lean toward grey, building depth through value rather than colour punch. At 46.8%, #0B0A0A functions less as a colour accent and more as a complete atmospheric environment. The saturated accent, #991F11, registers at 2.4% - sparse enough to feel like a deliberate surprise. A value spread of 78 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
