Gleaming Bluff
Five stops tuned to sit together without fighting — #00698e ink anchors the set, #96dcff opens it up, and #1995c5, #42b1e3, #69c0ea cross the middle in a analogous arrangement. Gleaming Bluff suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
