Hyacinth Bookshop
Five stops tuned to sit together without fighting — #940054 ink anchors the set, #ff9cc2 opens it up, and #c3407c, #e25d97, #ea78a6 cross the middle in a monochromatic arrangement. Hyacinth Bookshop suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
