The color green can change how you feel, too. Often, it makes you feel rested. It also makes time seem to pass by fast. Because of this, it's often used in waiting rooms. But the color gray makes you feel so rested, you may fall asleep!
Colors can even change the way your body works. When you see the color red, your heart may beat faster. Red can also make you feel hungry. That is why restaurants like to use red when they decorate.
Color is all around you. If you know how it makes you feel, you can use color power to help you!
