Values in Pieter Meulener rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #645537 delivers the chromatic peak at only 7.3% - a small shot of colour with outsized visual impact. The palette spans 47 value units: a measured range that delivers coherence over drama. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Pieter Meulener's complete body of work advances.
