I've got a pretty good size batch of white that has turned a cream color. I can add a bunch of white color to it and bring it back some but it only takes a heating or two and it is right back to where it was. Don't want to turn it black as I have 2 cups of black right now. If I were to turn it to a blue, would it hold up for a while or would it continue to discolor? Opinions appreciated. Thanks.CF
