What are the feng shui requirements for the color of bathroom tiles?

What color is the bathroom? Avoid big red and golden yellow in good feng shui. In geomantic omen, you can't use the color of fire, because the bathroom is water-based, which will cause fire and water to interfere with each other and bring adverse effects to people's health. Moreover, as a place to discharge filth and a hiding place for villains, the fire-colored tiles will make Shaqi fire, so the function of collecting Shaqi in the bathroom cannot be better played.
