Hickory Gallery
Five stops tuned to sit together without fighting — #005475 ink anchors the set, #7fc5eb opens it up, and #227ea8, #439ac5, #63a8cd cross the middle in a complementary arrangement. Hickory Gallery suits hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA for large text.
