Try to remember that when using colors in your magickal working be it with candles, poppets, colored water, altar clothes or whatever you choose, you can always mix and match.
FOR EXAMPLE:
For a healing you may use a WHITE altar cloth for purification. And three candles... Blue for healing, Green for a "abundance" of healing and Gold for "drawing" the healing to who you are doing this spell for. Also you may want to add things like a poppet made in blue cotton cloth or place the water in which you will cast the circle in a blue bottle set out on a moon lit night prior to the healing. There are many different combinations but listen you your heart. I will guide you in your magickal workings and let you know what is right for you.
Blessed Be!
