Candles can be used to "light" the spiritual darkness of a room. Have you ever noticed how a burning candle's light permeates a room? Colors can have an effect on the energy field around you and your home.
Colors have their own energy. The energy of each color, or its light-wave vibration, has an effect on the human body. They affect our moods and aid in healing. In magick, colors help you fine-tune your intent, focus your energy, and help your magick work. -- (Paraphrased from Wicca and Witchcraft for Dummies, by Denise Zimmerman and Katherine A. Gleason; Alpha Books; 2003)
A really wonderful article to read is from one of my favorite authors, Ellen Dugan, who has lots of info on color magick for each day of the week: http://www.llewellynjournal.com/article/710
