I'm very curious about this too.
At the opening of both Easy Street Records locations in Seattle there were a total of (I think) 5 Mike/Star 7"s and to my knowledge there were all RED. I know this because I was at each store opening (one was 7am the other 9am).
Then, at Sonic Boom in Ballard (Seattle area) we were told by the employees there that they were supposed to have 60 copies. All were signed and most appeared to be black, however there were some RED ones with Mike's signature on the sleeve.
Later in the day there was a tweet from Matt Vaughan of Easy Street stating that they again had the Mike/Star 7" back in stock at both locations but I have no idea what those colors would have been.
