Blue Hour palette
Denim Oasis
Five stops tuned to sit together without fighting — #006195 ink anchors the set, #9ad3ff opens it up, and #008cd3, #37a8f1, #60b8f6 cross the middle in a tetradic arrangement. Denim Oasis suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
