Retro palette
Fern Brook
Five retro stops with room to breathe — #782205 grounds, #a34e36 and #c16950 do the talking, #c97d67 softens, #e89982 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.
