Industrial palette
Spruce Abbey
Five industrial stops with room to breathe — #006e7e grounds, #209baf and #47b7cc do the talking, #6dc5d6 softens, #8ae3f4 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.
