Monochrome palette
Elder Beacon
Five monochrome stops with room to breathe — #00436b grounds, #1a6ba1 and #3a86be do the talking, #5895c5 softens, #73b1e3 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 as a text pair.
