Neon palette
Luminous Hollow
Five neon stops with room to breathe — #006218 grounds, #328d3d and #50a958 do the talking, #6db671 softens, #89d38d 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 for large text.
