It really does not matter what color the candles are. The reason to this is that it just gives you the right feeling and set of mind when you use the black candle but if you can fall into same sort of "trance" with using different colored candles go for it. I recommend for you to read Satanic scriptures by Peter Gilmore for more information about the subject.
Someone can correct me if I said something incorrect.
