Whispering Square
Five stops tuned to sit together without fighting — #6a2c5d ink anchors the set, #d99ec9 opens it up, and #945585, #b16fa0, #bb83ad cross the middle in a tetradic arrangement. Whispering Square suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
