Mid-key values give Paul de Longpré its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 2.3% is devoted to #793E31, yet that small allocation delivers the palette's entire chromatic tension. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Paul de Longpré's complete body of work advances.
