Steely Lighthouse
Five retro stops with room to breathe — #4761a6 grounds, #708bd1 and #8ba7ef do the talking, #9fb8f6 softens, #c4d6ff 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 for large text.
