Obsidian Square
Five stops tuned to sit together without fighting — #006762 ink anchors the set, #80dcd4 opens it up, and #00958e, #39b1aa, #62beb7 cross the middle in a complementary arrangement. Obsidian Square suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA for large text.
