Opera palette
Snowy Meadow
Five opera stops with room to breathe — #004c78 grounds, #0075b5 and #3191d3 do the talking, #55a0d8 softens, #72bcf7 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.
