Nicolas Poussin keeps values measured and balanced, a hallmark of tonal restraint. 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. #63562A delivers the chromatic peak at only 11.5% - a small shot of colour with outsized visual impact. The palette spans 54 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 7 sits within the larger chromatic argument that Nicolas Poussin's complete body of work advances.
