Everyone remember how to remember the colors of the rainbow: Just recall the name: Roy G Biv. It's that simple. R=Red O=Orange Y = Yellow (ROY) G = Green. Now you have Roy G. Add B = Blue I = Indigo and V = Violet. And that's how Roy G Biv helps you recite the color order of every rainbow you see. Yes, I know I have too much time on my hands, but let's hope the naming convention helps. Teach your grandchildren so they will always know the answer of the rainbow's colors
