Retro palette
Polar Cove
Five retro stops with room to breathe — #9b3b00 grounds, #db5700 and #fb7432 do the talking, #ff8f5d softens, #ffbca1 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.
