You look out your back window. It’s raining. It’s gray. You look out your front window. It’s sunny. It’s yellow. You step outside and look up. You see it. It’s what some people all an optical illusion but what most people call a rainbow. Starting with red the colors morph into each other. You see orange, yellow, green, blue, indigo and violet. Better than any pot of gold is the wide variety of colors Heat Transfer Vinyl World has to offer.
