Henriëtte Ronner-Knip sits in the centre of the value range, lending the palette a sense of even, sustained light. Henriëtte Ronner-Knip builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 4.7%, #9B663A carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 67 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 palette 4 of Henriëtte Ronner-Knip's sequence - a single chapter in a chromatic story told across many works.
