Petrichor palette
Polar Delta
Five stops tuned to sit together without fighting — #007072 ink anchors the set, #85e5e7 opens it up, and #009ea1, #3bbbbd, #67c8ca cross the middle in a analogous arrangement. Polar Delta suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
