I don't really agree with this theory. Even if the other fabrics in the quilt don't pick up and retain the blue, that doesn't mean that the blue won't continue to come off on the sheets, the hands, other things. It may wash out of all of them eventually, but who wants a bleeding fabric on their bed?
