Art Nouveau occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette orchestrates warmth above all else - reds, ambers, and siennas take the lead. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #DACDB6, is reserved to 6.1% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 56 units of the value scale - a span that creates natural depth.
