The value structure of Surrealism is mid-key: quiet, controlled, and cohesive. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #170F0B functions as the palette's exclamation mark: highest chroma, lowest percentage (7.9%). A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
