In terms of Feng Shui, can’t white be used for footing lines?

According to Feng Shui, white skirting lines will not be used. Because red and purple are the colors that mark the solemn boundary between yin and yang. It can suppress some evil spirits underground. If you feel the color is not good-looking, you can cover it with glossy plywood. It can also be left uncovered. After all, the base line is not the short part that people pay attention to. As long as you don't care too much, it won't have any impact.
