Sheriann, Bobquilt3 had a very interesting suggestion that I would never have thought of.
Like so many others have said, try (in this case) 2 or even 3 colour catchers with lots of water in the machine. I usually use them if I think there's even a slight possibility that something-- and it's usually red-- will run in the laundry.
I washed the cloth outer part of a new shower curtain last week which was white with large navy blue leaves on it. I didn't notice that the formerly white part was baby blue until I had taken it out of the dryer. And my dryer runs hot, even on the delicate setting. I rewashed it with several colour catchers and it came out as good as new. I was pleasantly surprised that the background turned white again after having been "heat set" in the dryer.
