Carl Larsson is high-key - luminous, open, and weighted toward light. Carl Larsson builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #282119, is reserved to 1.9% of the surface, where it acts as a focal punctuation. At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of Carl Larsson's sequence - a single chapter in a chromatic story told across many works.
