The value structure of Charles Gleyre is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #845A44, is reserved to 5.9% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 63 units of the value scale - a span that creates natural depth. 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 5 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
