This is an optional step. Your candles will come out a naturally milky white, but if you’d like to add a little color, you can use a nontoxic crayon or candle color block. I typically use 1/8-inch of red crayon per 16-ounces of wax flakes to get a soft pastel color. Want a brighter color? Use a little bit more, only adding color a bit at a time. Like food coloring, a small amount goes a long way. Simply melt your color along with your wax flakes. Warning: The color will look a lot brighter in the melted mixture but will turn a milky color as it cools.
