The dancing flames of candles have been used as a Witches’ tool for centuries. By setting the proper atmosphere, candles are used to help increase a spell’s power, or to influence a particular power. Candles absorb one’s personal energy and release this energy when burned. Candle color is very important when performing magick, for each color emits a particular vibration and attracts certain influences. The following list is meant to be used as a guide in choosing a candle color for your personal use. Please remember that color is another "tool" and you need choose what works best for you in your magickal workings. If you do not have the color mentioned for a particular need, allow your intuition and the [God] Goddess [to] guide you in choosing one for your purposes.
The candles you use should be ones you yourself make out of beeswax, using natural dyes and essential oils, if desired. Beeswax sheets are available at most hobby stores, and are a fast and easy way to make your own candles at home. Realizing this is not always possible, you may use what is readily available to you. Prior to using any candle in your workings you should cleanse the candle and anoint it with a small amount of oil during the waxing phase of the moon. This consecrates the candle and charges it with magickal energy. You can also carve or paint appropriate magickal symbols onto your candles, to further empower the candles with those energies. The heated tip [of a knife] works well for this purpose. It is best to use one candle per ritual or spell, and to not use a candle that has been used previously for another purpose. It is also best to allow the candle to burn out by itself, as blowing it out may disperse the energy contained within. [You may also use a candle snuffer.]
