Helene Schjerfbeck is high-key - luminous, open, and weighted toward light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #A88D65, is reserved to 7.0% of the surface, where it acts as a focal punctuation. 44 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that Helene Schjerfbeck's complete body of work advances.
