Pastel palette
Umber Heath
Five pastel stops with room to breathe — #005450 grounds, #00807b and #349b96 do the talking, #58a9a3 softens, #75c5c0 lifts. The split-complementary 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.
