The value structure of Luminism is mid-key: quiet, controlled, and cohesive. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Mid-saturation across the board: the palette has colour character without chromatic excess. #E2CEA0 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.2%). A value spread of 64 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
