There seems to be a lot of confusion over the color Indigo. Is it blue? Is it purple? Does it even exist?
A digitally painted Tiger Lily I created from a photo I took.
We've all been taught the colors in a rainbow when we were kids. Most of us know them by the acronym ROY G BIV (Red Orange Yellow Green Blue Indigo Violet). So we have been told it's there even if it is hard to really see in an actual rainbow in the sky.
I'm honestly not sure it fully deserves it's own color classification. That is something that has always bothered me going way back to my days at the Art Institute. It certainly is NOT a Primary, or Secondary color as we are taught in school.
So what gives?
Indigo is an in between tertiary color, like red-orange (rust) or blue-green (auqua), and just as there are hundreds of variations of those, there are many variations of what we call indigo. So it is really more like a "blue-violet".
Even the famed Isaac Asimov has been quoted as saying, "It is customary to list indigo as a color lying between blue and violet, but it has never seemed to me that indigo is worth the dignity of being considered a separate color. To my eyes it seems merely deep blue."^
The topic is even open for discussion over on the wikipedia page for Indigo where the various hues and shades of indigo are shown leaning towards violet, more than blue.
Indigo color charts available on Wikipedia ^^
I suppose it remains open for debate.
