Chambray Lagoon
Five stops tuned to sit together without fighting — #893422 ink anchors the set, #f9aa98 opens it up, and #b45f4c, #d27a66, #db8e7d cross the middle in a complementary arrangement. Chambray Lagoon suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
