Pastel palette
Perennial Lane
Five pastel stops with room to breathe — #006c6f grounds, #009a9e and #3bb6ba do the talking, #65c4c7 softens, #83e1e4 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.
