You're right, there are tons of colored fake around, including the red and the yellow (sometime advertised as spanish press) In Utero.
About Albini mix : the first batch of 2005 In Utero (German press) has the Albini mix. It's not a bootleg, catalogue number is 424 536-1. This German repress is still in print and available but I don't know if the later pressing has been rectified.
