Aurora palette
Opal Porch
Five aurora stops with room to breathe — #005e62 grounds, #008b91 and #37a7ad do the talking, #5eb4b9 softens, #7bd1d6 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.
