Obsidian Bluff
Five stops tuned to sit together without fighting — #005b4c ink anchors the set, #78ceb9 opens it up, and #008873, #35a48e, #5bb19d cross the middle in a tetradic arrangement. Obsidian Bluff suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
