Acid palette
Brumal Heath
Five acid stops with room to breathe — #007174 grounds, #009fa3 and #3cbcbf do the talking, #67c9cc softens, #85e6e9 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.
