Nebula palette
Sage Shrine
Five nebula stops with room to breathe — #811400 grounds, #b73b24 and #d65840 do the talking, #dd715b softens, #fc8d76 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 as a text pair.
