The Color of Candles

Hi! My close college friend is Jewish and resides in Montgomery, Alabama. She asked me to investigate if there is a particular tradition behind the colors of Chanukah candles sold in the retail stores. Or is it important that the candles be a certain color? I look forward to your reply.

There's no tradition regarding the color of the candles; so any color is okay, even plaid! Actually, it is preferable to use olive oil lamps, to commemorate the miracle of the oil.

Please note that the small colored Chanukah candles aren't long enough to use on Friday, because the candles must be lit before sunset and must remain alight for a half hour after dark.
