Botanical palette
Polar Clearing
Five botanical stops with room to breathe — #1a3f96 grounds, #426ac0 and #5b86de do the talking, #7196e2 softens, #8db3ff 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 as a text pair.
