Harald Sohlberg occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Harald Sohlberg tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #785C3C, registers at 7.4% - sparse enough to feel like a deliberate surprise. A value spread of 67 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Harald Sohlberg's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
