Industrial palette
Ember Alley
Five stops tuned to sit together without fighting — #005457 ink anchors the set, #75c5c8 opens it up, and #008084, #349c9f, #59a9ac cross the middle in a tetradic arrangement. Ember Alley suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
