This is from the Flex! website, "900 made, 5 different sleeves: 100 made with Hitler cover, unknown number of the others."
sounds right to me. The covers were in various colors on various paper stocks. There's really no consistency. Even the hitler covers I have seen in at least three colors and they were all legit from what I could tell.
Here's the infamous Hitler cover.. still seems like a sketchy cover idea to me, at best. Green one shown here and a below it a photo off ebay of a lighter colored cover.
and here are some other covers/colors:
