Clover Plaza
Five stops tuned to sit together without fighting — #7f1900 ink anchors the set, #f19580 opens it up, and #ac4832, #ca634c, #d27965 cross the middle in a split-complementary arrangement. Clover Plaza suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
