Felix Vallotton is high in key: pale, luminous, and filled with optical air. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. At 1.5%, #CB9E5C carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 61 units of value range underpin the palette's structural clarity: the eye always knows where light falls. 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 Felix Vallotton's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
