Johan Jongkind keeps values measured and balanced, a hallmark of tonal restraint. Temperature is cool-dominant, with blue and green families claiming the largest areas. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #5E6990, is reserved to 3.8% of the surface, where it acts as a focal punctuation. The full value range is 57 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Johan Jongkind preferred, made measurable.
