The value structure of Pieter Casteels II is mid-key: quiet, controlled, and cohesive. Pieter Casteels II builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #715335 is not a small accent - at 6.9% it qualifies as a major presence and gives the palette its chromatic identity. At 50 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 2 sits within the larger chromatic argument that Pieter Casteels II's complete body of work advances.
