Blue Hour palette
Spiced Reef
Five stops tuned to sit together without fighting — #004567 ink anchors the set, #6eb4e2 opens it up, and #006ea0, #2f89bd, #5298c4 cross the middle in a split-complementary arrangement. Spiced Reef suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
