We all know that our mood has colors. So it will create harmony if we decorate surrounding with matching colors as well, otherwise it will not look and feel comfortable, isn't it? The color of our mood can change, so that it requires surrounding colors being changeable as well. Or, the change of surrounding colors can cause the change of our mood, or we need to adjust our mood to match surrounding colors. In short, the mood and surrounding colors need to be coordinated to maintain harmony. Also, we need to have enough options for the coordination. The result is a colorful life!
Right, my activity is to match my color of mood or to make my color of mood.
