Hilma af Klint is strongly light-biased - shadow is suggested rather than declared. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The most saturated colour, #AB7B56, is reserved to 3.2% of the surface, where it acts as a focal punctuation. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. In the context of Hilma af Klint's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
