Leaden Grove
Five stops tuned to sit together without fighting — #37347b ink anchors the set, #a0a4e6 opens it up, and #5c5da4, #7578c1, #8589c8 cross the middle in a split-complementary arrangement. Leaden Grove suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
