Pastel palette
Halcyon Prairie
Five pastel stops with room to breathe — #005819 grounds, #00862b and #33a247 do the talking, #58af62 softens, #75cc7e lifts. The triadic 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.
