Sable Chapel
Five monochrome stops with room to breathe — #006f7e grounds, #009db1 and #3bbace do the talking, #67c7d8 softens, #85e5f6 lifts. The analogous 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.
