Pastel palette
Greige Bluff
Five pastel stops with room to breathe — #214e97 grounds, #4b78c1 and #6594df do the talking, #7ca4e5 softens, #9ac1ff 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 for large text.
