A house can do so much in helping you succeed or fail at your endeavors. There are a lot of factors that you have to consider, and this just not includes the position of your house or the position where your furniture are placed. Included in the considerations that you have to make is the color that you will use for your home.
And it really depends on the personality that you have. If the color of your room is OK by Feng Shui standards but it's actually clashing with your own personality, then there won't be any good effect. The harmony inside of a room is not only dependent on the energies that it emits. It is also dependent on the energies that you emit yourself.
For example, we already know that blue is a color that you can employ if you want a relaxing home, or if you are quiet yourself. Blue, especially the lighter tones of it, is an expert at calming the nerves of an agitated person. If you want to have a harmonious relationship with your loved ones all year long, you might want to choose this color.
On the other side of the spectrum, there's the color yellow, which represents jolliness and joy. If you like to jump around and sing for joy, yellow is the best color for you. Then there's also red, which signifies romance. I think this kind of color is best suited for the master's bedroom, so that it may ignite the spark between you and your spouse. You could then mix and match these colors (plus a lot more) to suit your personality considerably.
The best way to know what color best suits your personality is to take a psychological test. It gives you a lot of insight not only about the color you need, but also insight on your own personality. Some people just don't know themselves. This is a perfect way to start your own journey of self-discovery and, eventually, the journey of harmonizing with your own self.
