Prairie palette
Opal Lane
Five prairie stops with room to breathe — #006d80 grounds, #199ab2 and #43b6cf do the talking, #6ac4d9 softens, #88e2f7 lifts. The analogous bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
