Lichen Brook
Five stops tuned to sit together without fighting — #005070 ink anchors the set, #74c1ea opens it up, and #007aa8, #3396c5, #57a4cd cross the middle in a analogous arrangement. Lichen Brook suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
