Robert Delaunay distributes its values across the middle register, creating harmony without high contrast. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #DE150E functions as the palette's exclamation mark: highest chroma, lowest percentage (8.3%). 85 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. Palette 2 sits within the larger chromatic argument that Robert Delaunay's complete body of work advances.
