Yaël: I'm here with Roy G. Biv, the man who claims to own the rainbow.

Roy: Hello everyone.

Y: Now you...

R: Can I just say what a great job I think you all are doing here at Moment of Science?      I'm a longtime listener.

Y: Thanks, Roy. But let's cut to the chase. How can one person own the rainbow? I      mean, a rainbow isn't a physical object. It's a visual phenomenon caused by the way      light refracts off of water droplets in the air. Right?

R: That's right Yaël. But just what colors are there in a rainbow? And how do they go?

Y: Well...

R: Is it Green, Pink, Hazel, Aquamarine? How about Orange, Blue, Fuscia, Magenta?      Or is it different every time? Do you know?

Y: Well, actually...now that you mention it...

R: No! You don't know! Nobody does! That's why you need me: Roy G. Biv.

Y: I don't quite follow.

R: Roy G. Biv, Yaël, that's my name. Roy G. Biv. Can you remember it?

Y: Roy G. Biv.

R: That's right. Roy G. Biv. Now you know what colors are in the rainbow, and what      order, too.

Y: Oh yeah?

R: Let's do it together. Red. Orange. Yellow. Green...

Y: ...Blue. Indigo. Violet. I get it! Roy G. Biv.

R: That's the ticket. Remember my name and you'll never have trouble remembering      what color goes where. By the way, this works any time white light is broken into its      component parts. That sequence of colors is called the "spectrum."

Y: Red, Orange, Yellow, Green, Blue, Indigo, Violet. Thanks, Roy!

R: Don't mention it.
