The first is that it is best not to use too much red or black as the main color in the house, because too much red or black will make people impulsive. It is also suggested that the paint on the wall surface should improve its purity and lightness to achieve saturation, which is what we call positive color.
Secondly, in China Feng Shui, smallpox represents the sky, the floor represents the ground, and the wall represents people. The color of the wall should be between the ceiling and the floor, that is, deeper than the ceiling and shallower than the floor, so that heaven, earth and earth can achieve harmony.
Third, the sky is clear and the ground is muddy: the color of the ceiling should be as light as possible, and the color of the floor should be darker than the ceiling. Otherwise, family members will put the cart before the horse.
