Feng shui colors play an important role in harmonizing your home, especially if you’re trying to find the best feng shui colors for your South-facing front door. This is because each of the five elements (water, fire, earth, metal and wood) has an affinity with each of the five Chinese elements (fire, earth, metal, water and wood). While there are no strict rules on what color you should paint your front door, there are certain colors that are most likely to bring good luck to your home if they are found on the right side of your house.
