I just opened and checked my copy of Coraline, the glasses it comes with are red/blue. not sure if my red/blue set is specific to the Collector's set that I have, but I would imagine any copy that comes with glasses would be red/blue as well.
Since you specifically mentioned the Evil Empire by name, I checked their site and they have a Blueray + standard DvD copy that comes with 4 glasses (does not specify red/blue or not) - $15. http://www.walmart.com/ip/11082067
you can also check to see if they have one in stock near you
nevermind, I just tested them, they are the Red/Cyan
Just find some place that uh, sells translucent red and blue material of some sort, cut some out, make some kinda frame for best results, perhaps out of cardboard. Or you can just find them wherever dunno. A craftstore or something would have the materials, dunno about actual glasses. Movies used to give those out way back in the day.
