Petrichor palette
Bronze Delta
Five stops tuned to sit together without fighting — #005e68 ink anchors the set, #7bd0dd opens it up, and #008a99, #37a6b5, #5eb3c0 cross the middle in a tetradic arrangement. Bronze Delta suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
