If you are a lover of bold colors, perhaps prosperity is already knocking on your door. But purple is believed to be most associated with wealth and good luck. Painting any of the walls of your home with this color will not only improve the financial wealth but also add a touch of elegance to the room. If you do not prefer such bold colors, you can also keep plants that grow purple foliage. Even soft cushions, pillows, or any specific piece of furniture of this color will work!
