Blue Hour palette
Halcyon Oasis
Five stops tuned to sit together without fighting — #005268 ink anchors the set, #75c3df opens it up, and #007d9c, #3399b8, #58a6c2 cross the middle in a split-complementary arrangement. Halcyon Oasis suits bike-shop liveries that survive mud and sun. The darkest and lightest stops clear AA for large text.
