So if you absolutely have no sense of fashion the color wheel should help you get started. For example if you are confused between what color shirt will go with that grey color pant then follow the color theory. According to color wheel theory, colors combine harmoniously if they are on opposite sides of the wheel! Isn't this superb?!
Nature provides a perfect departure point for color harmony. In the illustration above, red yellow and green create a harmonious design, regardless of whether this combination fits into a technical formula for color harmony.
