Acid palette
Inked Meadow
Five acid stops with room to breathe — #004659 grounds, #00708d and #308ba9 do the talking, #5299b3 softens, #6eb5cf lifts. The tetradic bones keep it coherent across event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
