Charles Angrand works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Mid-saturation across the board: the palette has colour character without chromatic excess. The saturated accent, #C96537, registers at 4.5% - sparse enough to feel like a deliberate surprise. Value range is moderate at 51 units - enough contrast for legibility, not so much as to fragment the tonal unity. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Charles Angrand's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
