Light floods Charles Gleyre; the palette keeps values pale and airy across its range. Charles Gleyre builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The chromatic peak belongs to #675A3B, and at 6.4% it dominates, not decorates. 45 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Charles Gleyre's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
