Obsidian Caravan
Five stops tuned to sit together without fighting — #006e6c ink anchors the set, #83e3df opens it up, and #009c99, #3bb8b5, #65c6c2 cross the middle in a monochromatic arrangement. Obsidian Caravan suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
