Aurora palette
Sumac Grove
Five stops tuned to sit together without fighting — #1c3d7a ink anchors the set, #8bace5 opens it up, and #4365a3, #5c80c0, #7090c7 cross the middle in a analogous arrangement. Sumac Grove suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
