Values in Art Nouveau tilt decisively toward white, giving the palette its luminous character. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #F3EDD5 claims 25.9% of the surface, functioning as the work's tonal foundation. #DED2AF delivers the chromatic peak at only 10.9% - a small shot of colour with outsized visual impact. 61 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
