Dear Uncle Dixer: Why do people prefer deep-red color for the front door? Is it the best Feng Shui color for the front door? Thanks!
Answer: Red is an auspicious color to the Chinese. It is correlated to the Fire Phase that grows upward and makes progress. It is a happy color and makes one feel positive.
Red is associated with blood as blood is Vital Qi (Qi that keeps us alive). So, if you are to use red, it is better to use fresh red rather than deep red. But sometimes deep red is used a Compass Feng Shui reason, but it is too complicated to explain here.
No color is ever the best or the worst in Feng Shui. It depends on the situation.
