We Have the Facts Album Art

The other day, I was ripping some of my old CDs to put on my iPod (old, I know). I got to We Have the Facts and it reminded me that mine is different than most others, but I never understood why. It simply has the color pattern of the dots inverted or just slightly different. Was it just a first running kind of thing? Or did they change for some other reason? Always been curious about this. I bought it pretty soon after it was released through CDNow (again, old, I know), but, aside from the colors, there doesn't appear to be anything super remarkably different about it.

Anybody know?
