Lovely Rug

So, I have blue rugs on the floor in the kid's bathroom and very light cream/brown rugs on the floor in my bathroom. The ones in my bathroom WERE really pretty. The kids' rugs have had reason to be washed a number of times, so I didn't think anything of throwing them in together. The blue ones still look normal, but the pretty ones in my bathroom are now a REALLY ugly gray with lighter patches. Yuck! I guess I will have to pick up some RIT dye and see if I can come up with a slightly less bad color.
