What looks like a colour wheel on the sleeve back is actually a key to deciphering the codes on the sleeve edges of Blue Monday, Confusion and this release. The outer ring of the wheel represents every letter in the alphabet with the solid bars doubling as numbers 1-9. The solid light green strip pointing "north" represents the letter "A" (and 1) the solid yellow bar to the right is "B" (and 2)and so-on ending with the split bar of pink and yellow for "Z". The first four boxes on Power Corruption and Lies decode as FACT, the last is split into two for the numbers 7 and 5.
