The value structure of Gustave Loiseau is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 7.6%, #8A6E4E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range of 41 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 17 of Gustave Loiseau's sequence - a single chapter in a chromatic story told across many works.
