Nebula palette
Cardamom Gallery
Five stops tuned to sit together without fighting — #007163 ink anchors the set, #85e7d4 opens it up, and #00a08c, #3cbda8, #67cab7 cross the middle in a tetradic arrangement. Cardamom Gallery suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
