Harbor Reef
Five stops tuned to sit together without fighting — #8a2a5c ink anchors the set, #fca4ca opens it up, and #b65784, #d4729f, #dd88ae cross the middle in a tetradic arrangement. Harbor Reef suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
