Cobalt Archive
Five stops tuned to sit together without fighting — #00505e ink anchors the set, #74c1d2 opens it up, and #007b8f, #3396ab, #57a4b5 cross the middle in a split-complementary arrangement. Cobalt Archive suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
