Blue Hour palette
Silken Harbor
Five stops tuned to sit together without fighting — #006c80 ink anchors the set, #83e1f9 opens it up, and #0099b4, #3bb5d1, #65c3db cross the middle in a monochromatic arrangement. Silken Harbor suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
