The best color is the color that blends in and resonates with the design and color of the house and its neighborhood. There is no such thing called ‘the’ best color! Some feng shui books and teachings suggest that using red for the front door as it is an auspicious color. This concept comes from Chinese tradition. In ancient China, there was a very strict building code; people were allowed to build a house with so many rooms and to have a particular color for their door, based on their status in government and society. Most civilians were not allowed to use red color for the door. Red color could only be used for ranking official’s family. Therefore, a red door represented the rich and noble. However, this may be a cultural value, but not a universal value. If something is not universally true, it’s not feng shui.
