Neon palette
Lupine Archive
Five neon stops with room to breathe — #00494c grounds, #007478 and #318f93 do the talking, #539c9f softens, #6fb9bc 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 as a text pair.
