Peter Saville's design for the album had a colour-based code to represent the band's name and the title of the album, but they were not actually written on the original UK sleeve itself (they were present on some non-UK versions), although the catalogue number "FACT 75" does appear on the top-right corner. The decoder for the code was featured prominently on the back cover of the album and can also be seen on the "Blue Monday" and "Confusion" singles and for Section 25's album "From the Hip".
