Indigo Matters


The rainbow flag is meant to be inclusive, right?

All of the colors are represented.


As anyone that has taken a science class knows, the mnemonic for the colors of the rainbow is Roy G Biv.
Biv = Blue       Indigo      Violet

But none of the rainbow flags I have ever seen show indigo. They only show six colors.

Which brings up the question: Who does indigo represent and why are they excluded?
