Nebula palette
Heather Reef
Five stops tuned to sit together without fighting — #650072 ink anchors the set, #d587e0 opens it up, and #91379e, #ae53bb, #b86bc2 cross the middle in a monochromatic arrangement. Heather Reef suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
