The value structure of Eugène Jansson is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #B2A753 - appears at just 5.9%, deployed as a precision accent against the quieter ground. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. These proportions encode Eugène Jansson's instinctive sense of how much of each quality the eye can hold.
