Jewel palette
Nectar Fjord
Five jewel stops with room to breathe — #004b6e grounds, #0075a7 and #3190c4 do the talking, #559fcb softens, #71bce9 lifts. The monochromatic 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.
