That's when you have an actual problem. If the white picks up the blue then you need to determine if it'll wash back out. It generally will because you have to do something chemically to set modern chemical dyes. Most of the time a wash with lots of water and OxyClean will take out excess dyes fabrics have picked up. There used to be a product made just for taking out dyes that other fabrics had picked up. I think it was made by Carbonara but I wouldn't swear to it.
