Birch Lagoon
Five stops tuned to sit together without fighting — #810937 ink anchors the set, #f28fa3 opens it up, and #ad415d, #cc5d77, #d47488 cross the middle in a triadic arrangement. Birch Lagoon suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
