Acid palette
Elder Fen
Five acid stops with room to breathe — #00576a grounds, #00829e and #359eba do the talking, #5aacc4 softens, #77c8e2 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 for large text.
