Tidal Gallery
Five stops tuned to sit together without fighting — #751611 ink anchors the set, #e59084 opens it up, and #a0453b, #be6054, #c6756a cross the middle in a split-complementary arrangement. Tidal Gallery suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
