Bitter Lagoon
Five stops tuned to sit together without fighting — #741d00 ink anchors the set, #eb9076 opens it up, and #a64327, #c45e42, #cc745c cross the middle in a analogous arrangement. Bitter Lagoon suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
