Pumice Square
Five stops tuned to sit together without fighting — #00737f ink anchors the set, #8fe8f4 opens it up, and #28a0ae, #4dbdcb, #72cad6 cross the middle in a triadic arrangement. Pumice Square suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
