Values in Paul Serusier rest in the mid-range - neither dramatically lit nor steeped in shadow. Paul Serusier builds on cool foundations: the palette favours the blue-cyan-green arc. Mid-range chroma keeps the palette grounded - colourful but not strident. #C36123 delivers the chromatic peak at only 11.6% - 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. Palette 4 sits within the larger chromatic argument that Paul Serusier's complete body of work advances.
