Blue Hour palette
Citrus Depot
Five stops tuned to sit together without fighting — #006c89 ink anchors the set, #8ee0ff opens it up, and #0099c0, #3bb6de, #66c4e6 cross the middle in a tetradic arrangement. Citrus Depot suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
