Copper Estuary
Five monochrome stops with room to breathe — #00676d grounds, #11949c and #3eb0b8 do the talking, #65bec4 softens, #83dbe1 lifts. The triadic 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.
