Ebony Atelier
Five stops tuned to sit together without fighting — #313787 ink anchors the set, #9aa9f2 opens it up, and #5561b1, #6e7ccf, #7f8dd4 cross the middle in a triadic arrangement. Ebony Atelier suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
