The high-key values of Carl Abraham Rothstén give it an effulgent, almost bleached quality. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #644224 delivers the chromatic peak at only 8.2% - a small shot of colour with outsized visual impact. A value spread of 55 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. This is palette 1 of Carl Abraham Rothstén's sequence - a single chapter in a chromatic story told across many works.
