Nebula palette
Oaken Atelier
Five nebula stops with room to breathe — #4f3588 grounds, #755fb2 and #8f7ad0 do the talking, #9d8cd6 softens, #b9a8f4 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 as a text pair.
