The value structure of Godfrey Kneller is mid-key: quiet, controlled, and cohesive. Godfrey Kneller keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #E4CFA2 delivers the chromatic peak at only 5.7% - a small shot of colour with outsized visual impact. A value spread of 76 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. These proportions encode Godfrey Kneller's instinctive sense of how much of each quality the eye can hold.
