Mid-key values give Art Nouveau its characteristic quietness - nothing blazes, nothing disappears. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 5.8%, #904F3A carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 56 units of the value scale - a span that creates natural depth.
