Burnished Shrine
Five stops tuned to sit together without fighting — #00557a ink anchors the set, #77c6f6 opens it up, and #007fb4, #349bd1, #5aaad8 cross the middle in a analogous arrangement. Burnished Shrine suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
