Gleaming Heath
Five stops tuned to sit together without fighting — #004a61 ink anchors the set, #70bad9 opens it up, and #007496, #318fb2, #549dbb cross the middle in a split-complementary arrangement. Gleaming Heath suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
