Values in Regionalism rest in the mid-range - neither dramatically lit nor steeped in shadow. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #A0674A, registers at 5.7% - sparse enough to feel like a deliberate surprise. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
