Is indigo really a color in the rainbow?

Yes, Sean, it is. But it is a color that the human eye is not very sensitive to so we do not see it very well. It's frequency is between blue and violet, both of which we see better.

Larry Krengel

No. Although all the blues in a rainbow do contain some red, there is no place in the rainbow where a deep enough blue combine with enough red to make indigo. But isn't ROYGIV easier to pronounce than ROYGBV?
