How to Remember Color Order of Spectrum and Rainbow

Remembering the list order of the rainbow and visible light color spectrum is easy: ROYGBIV.

Additional wavelength, rainbow, sunset, laser images and information resources were added afterwards for folks who might find them interesting. Images can be clicked to be enlarged. But first, The Quick and Easy Way to Remember Rainbow and Spectrum Colors...

An Introduction to Mr. Roy G. Biv

Mnemonic Trick to Remember Order of Colors in the Visible Light Spectrum and Rainbows

His name is Roy G. Biv.

Note the first letter of each color in the visible light color spectrum map above. If you can remember the name, Roy G. Biv, then you have accomplished your goal.

ROYGBIV - The Color List and Order of the Visible Light Spectrum and Rainbow

  • Red, Orange, Yellow, Green, Blue, Indigo, Violet.
If you are interested in more information about the visible spectrum, wavelengths, light, colors, etc.; there are all sorts of additional information and resources below.

The List and Order of Visible Spectrum Wavelengths

Visible light wavelengths.

Visible light wavelengths

  • Red: The lower and longer wavelengths.
  • Violet: The higher and shorter wavelengths.

An Expanded Electromagnetic Spectrum List

There really isn't that much more to it.
  • Gamma Rays
  • X-Rays
  • Infrared
  • Red Orange Yellow Green Blue Indigo Violet
  • Ultraviolet
  • Microwaves 
  • Radio Waves
Interesting how the visible spectrum is right in the middle.

An Expanded Electromagnetic Wavelength Image

This image came from a NASA page with all sorts of additional information and resources on it, well worth a visit.

Rainbows - Nature's Natural Prisms

This NOAA/NASA page will tell you everything you would ever want to know about rainbows, how they are formed, etc. Rainbow images are free, public domain.

Lasers - Otherwise Known as Light With an Attitude

Here is an introductory page on How Lasers Work. Laser images are free, public domain.

The End

I hoped you liked the images and additional information resources. Feel free to use the images as desktop or other screen backgrounds, Pinterest pinning or other social media uses, etc.

So. What is the order of colors in a rainbow or the visible light spectrum? 😁
