Midcentury palette
Opal Prairie
Five stops tuned to sit together without fighting — #005f3a ink anchors the set, #7ad3a2 opens it up, and #008d58, #36a972, #5cb686 cross the middle in a complementary arrangement. Opal Prairie suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
