Blue Hour palette
Seaside Harbor
Five stops tuned to sit together without fighting — #005087 ink anchors the set, #7fc1ff opens it up, and #0079c7, #3295e5, #58a5ea cross the middle in a tetradic arrangement. Seaside Harbor suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
