Sorrel Hollow
Five stops tuned to sit together without fighting — #00494f ink anchors the set, #70b9c0 opens it up, and #00747d, #318f98, #539ca4 cross the middle in a triadic arrangement. Sorrel Hollow suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
