Aurora palette
Dewey Gazebo
Five aurora stops with room to breathe — #3730ab grounds, #595fd6 and #717bf5 do the talking, #838ff7 softens, #a3afff 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 as a text pair.
