Sorrel Lagoon
Five stops tuned to sit together without fighting — #006470 ink anchors the set, #7fd8e6 opens it up, and #0091a1, #38adbd, #61bbc8 cross the middle in a analogous arrangement. Sorrel Lagoon suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
