Psychology teaches us that color affects mood. While not everyone may feel the same way about certain colors, there are shades and hues that are seen to affect most people in a particular way. By keeping that in mind, you can make choices about the colors you use for the rooms in your home and the art you choose to put on the walls. When you understand colors and how they make you feel, you'll be able to pick your decor more easily and find just the right paint options for your house. Art that you put on the walls can also be a part of your use of color.
