I've had excess dye or bleeders from brown, black, green, blue, purple, red, orange, and YELLOW fabrics. By the way, some yellows can be quite tiresome to try to get rid of.
As Lori S said - each quilter develops his/her guidelines for fabric prep and what his/her comfort level is in using 'straight from the store' fabrics
PS - I do not rely on the brand or the source - I've had a Moda red spill color, I've had inexpensive no-name fabrics from WalMart that seem to be completely colorfast. I've had VIP reds that are very colorfast. I've had some VIP reds that have excess dye. I can't tell by looking.
