Halcyon Foundry
Five stops tuned to sit together without fighting — #2e3082 ink anchors the set, #95a2ec opens it up, and #515aab, #6a75c8, #7b86ce cross the middle in a tetradic arrangement. Halcyon Foundry suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
