Halcyon Beacon
Five stops tuned to sit together without fighting — #00626e ink anchors the set, #7fd5e4 opens it up, and #0b8e9f, #3baabb, #62b8c6 cross the middle in a monochromatic arrangement. Halcyon Beacon suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
