The first step to candle magick is to determine what color candle you will need. You can use whatever you feel is best but for some of my prefences here's a brief chart:
Silver -Goddess energy(moon)
Gold -God energy(sun)
Black -creating new beginnings, banishing, repelling, communication with spirits
White -universal energy, purifying, protection, truth, peace
Red -FIRE-will, passion, change, life force
Pink -love, reconciliation, friendship, harmony
Orange -legal matters, luck, success
Brown -nature, home, wisdom
Yellow -AIR-stimulates mental powers, learning, creativity
Green -EARTH-calming, grounding, healing, prosperity, money, fertility, balance
Blue -WATER-healing, emotions, spirit, cleansing, calming, meditation
Purple -spiritual strength, power, link to higher planes
