Rustic Library
Five stops tuned to sit together without fighting — #18368f ink anchors the set, #86aafa opens it up, and #3e61b9, #577cd7, #6c8ddb cross the middle in a triadic arrangement. Rustic Library suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
