Separating? I've done the same recipe for a while now but I've never color it, well just airbrushed it and it's perfect, but last night I took some out of the container to colored it black and when I was mixing it..... it wouldnt take the color and became watery, I ended up with a pool of black water in the bottom and a lumpy greysh BC on top! 
I really need black BC for some scroll work and I'm afraid it will keep bleading after I use it (if I get the color I want), but my worst fear is that the white one also separates, I don't even want to take it out of the fridge 
( it look fine so far, but I made the "black one" from the same batch! Why did it happen, and how can I fix it? Help please....!!!
You could always try to add the candy coloring to the batch and see if it saves it. It can't hurt to try. You can also get candy colors by Wilton at Michael's. They are used to color their candy melts.
