Light floods Paul Quinsac; the palette keeps values pale and airy across its range. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #8C91BD delivers the chromatic peak at only 6.4% - a small shot of colour with outsized visual impact. The full value range is 58 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 1 sits within the larger chromatic argument that Paul Quinsac's complete body of work advances.
