Happy birthday to you; your candles burn blue-or green or red or purple. Multi-color is the new yellow when you're lighting these special candles made from organic and inorganic salts and safe metals (such as magnesium). Not only are the flames colorful, but Rainbow Moments party candles are easy to blow out-ensuring that the birthday child's wish comes true. And because the candles are not made of wax, any candle drips are water soluble and easily cleaned up with a damp cloth.
