Choose one color (you can use different shades, though!) , and color in. Depending on what color it is, it can set the mood.
Yellow = Bright
Orange = Depends (to me, it sets a calm but still energetic mood)
Red = Depends (not necessarily anger)
Blue = Calmness and relaxation, or just quietness (sometimes sadness, but not necessarily)
Green = Calmness, nature, sometimes envy
Purple = Depends
Pink = Depends
