Blue Hour palette
Cobalt Kiln
Five stops tuned to sit together without fighting — #005384 ink anchors the set, #7ec4fd opens it up, and #207cbb, #4198d9, #62a7df cross the middle in a split-complementary arrangement. Cobalt Kiln suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
