Stormy Reef
Five stops tuned to sit together without fighting — #004367 ink anchors the set, #6db2e3 opens it up, and #006ca1, #2f87be, #5196c5 cross the middle in a tetradic arrangement. Stormy Reef suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
