Values in Art Nouveau tilt decisively toward white, giving the palette its luminous character. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #AA513A functions as the palette's exclamation mark: highest chroma, lowest percentage (1.5%). The value range spans 60 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.
