Aurora palette
Indigo Square
Five stops tuned to sit together without fighting — #003a84 ink anchors the set, #76aaf8 opens it up, and #2762b7, #427dd5, #5c8ed9 cross the middle in a split-complementary arrangement. Indigo Square suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
