Monochrome palette
Flint Lodge
Five monochrome stops with room to breathe — #005f83 grounds, #008abc and #37a6da do the talking, #5fb5e1 softens, #7cd2ff 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.
