What color should be used for the door facing south?

The colors used for doors facing south can refer to the traditional Chinese Five Elements Theory. The south belongs to fire, and colors that are helpful for water and fire can be used. Specifically, green belongs to wood, has a germination effect, and represents spring, health, and peace; red belongs to fire, has a warming effect, and represents passion, power, and sincerity. Therefore, green and red can be used for doors facing south. At the same time, black belongs to water, has a nourishing effect, and represents winter, coldness, and astringency; blue belongs to water, has a nourishing effect, and represents autumn, refreshing, and openness. Therefore, black and blue can also be considered.

However, it should be noted that color selection should also take into account the personal five-element attributes and the five-element likes and taboos of family members. For example, if the owner's five elements like water, then black and blue should be given priority when choosing colors instead of red and green.

To sum up, colors such as green, red, black or blue can be used for south-facing doors, but it is best to decide based on the personal five-element attributes and the five-element likes and taboos of family members.
