Helene Schjerfbeck is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #98804F, is reserved to 11.0% of the surface, where it acts as a focal punctuation. The value range of 49 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Helene Schjerfbeck's complete body of work advances.
