Obsidian Hollow
Five tropical stops with room to breathe — #980011 grounds, #cd3937 and #ed5852 do the talking, #f3746b softens, #ff9f95 lifts. The monochromatic 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.
