This past weekend at the Death Cab for Cutie show at the Greek Theatre in Berkeley, we witnessed one of the biggest, brightest rainbows I’ve ever seen. While celebrating the super rainbow I became overwhelmed with excitement and started shouting ROY G BIV over and over. You know… Red, Orange, Yellow, Green, Blue, Indigo, Violet… the colors and order of colors in a rainbow that we all learned when we were 7. Well this sparked a debate between me and Dave. He said the whole inclusion of indigo is some sort of conspiracy/scam. He said indigo doesn’t really exist. It isn’t a primary color and it isn’t a secondary color… there is nothing between blue and violet… it should be ROY G BV.
Turns out indigo isn’t really a color (at least not one in the rainbow and/or optical spectrum).
According to Wikipedia: Indigo is the color on the electromagnetic spectrum between about 420 and 450 nm in wavelength, placing it between blue and violet. Although traditionally considered one of seven divisions of the optical spectrum, modern color scientists do not usually recognize indigo as a separate division and generally classify wavelengths shorter than about 450 nm as violet.
First Pluto gets taken away, and now indigo? I feel like I need to redo 3rd grade science so I can get up to speed on what still exists.
On another note, how do I go about becoming a modern color scientist? Sounds fun!
