Midnight Estuary
Five stops tuned to sit together without fighting — #005793 ink anchors the set, #90c9ff opens it up, and #0080d4, #349cf3, #5bacf6 cross the middle in a monochromatic arrangement. Midnight Estuary suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
