Retro palette
Glassy Bazaar
Five retro stops with room to breathe — #195f9e grounds, #4b89c8 and #66a5e6 do the talking, #80b5ed softens, #a6d1ff 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.
