Opal Boulevard
Five stops tuned to sit together without fighting — #006b79 ink anchors the set, #82dff0 opens it up, and #0098ab, #3ab4c8, #64c2d2 cross the middle in a monochromatic arrangement. Opal Boulevard suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
