Light floods Eugène Grasset; the palette keeps values pale and airy across its range. Eugène Grasset builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 7.5% is devoted to #8B6446, yet that small allocation delivers the palette's entire chromatic tension. Spanning 51 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. 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 Eugène Grasset's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
