Polar Estuary
Five stops tuned to sit together without fighting — #345500 ink anchors the set, #9cc772 opens it up, and #53810d, #6d9d34, #81aa56 cross the middle in a tetradic arrangement. Polar Estuary suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
