Jean Arp works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. 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. A single dominant - #FFFDDF at 39.5% - sets the character of the whole composition. #ECE5D0 is not a small accent - at 1.7% it qualifies as a major presence and gives the palette its chromatic identity. The value range spans 73 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Jean Arp's sequence - a single chapter in a chromatic story told across many works.
