Retro palette
Velvet Abbey
Five retro stops with room to breathe — #7a5d00 grounds, #ab8413 and #c8a03b do the talking, #d3b162 softens, #f1ce7e lifts. The analogous 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.
