Yellow/Gold: Ruled by the Sun. Devotional offerings; beauty, happiness, joy and renewal. Relieves depression. Like orange, also attractive. Ruler of the soul. Devotional candles to the African Love Goddess Ochun are best done in yellow, with copper, blue, green, gold and/or silver glitter.
Of course common sense says, in general DO NOT LEAVE A CANDLE BURNING UNATTENDED IN AN UNSAFE MANNER. SUGGESTION PLACE CANDLE IN A BOWL OF WATER OR SNUFF OUT WHEN LEAVING YOUR HOME.
