Monochrome palette
Pumice Glade
Five stops tuned to sit together without fighting — #00567a ink anchors the set, #78c8f6 opens it up, and #0081b3, #349dd0, #5babd8 cross the middle in a analogous arrangement. Pumice Glade suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
