As LdyGry pointed out, you can use a white candle to substitute for any color.
While it does have things associated with it that may not seem like it would fit, the most important thing to remember about white if you are using colors for representation is that white is the substitute for any color. Red, blue, black..doesn't matter. White can stand in for it.
on that note on colours i will like to add the counter point that they have meaning not only because we say so its cause they hold certain energies. Different colours carry various different frequencies of energy doing different functions. I do not think it is wise to over look this, everything in the universe has a meaning and a purpose nothing . Same thing relating to our chakras, they carry various kinds of frequencies and colours which relate to those frequencies.

This idea of coloured candles is very "modern" in witchcraft. No witch had coloured candles in ancient times. Candles were not believed to have any "power" at all! They were merely used for seeing in the dark when casting indoors. A single candle may, of course, be used as "a focal point"; but in that case it is the flame that is important,not the colour of the candle.
