Blue Hour palette
Copper Lighthouse
Five stops tuned to sit together without fighting — #00698e ink anchors the set, #96dbff opens it up, and #3d93bb, #5bafd8, #79bee1 cross the middle in a split-complementary arrangement. Copper Lighthouse suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
