Violet in the rainbow is not a purple hue, it is a deep blue. Illustrations often color it more purplish but that is inaccurate

- bryanlarsen 2y agoYou usually can't see the really purple-y violet in a rainbow because it's quite dark -- it's easily absorbed by the atmosphere and our color cones aren't very sensitive to that wavelength. But it's there if you amplify it.
- stvltvs 2y agoExactly this, purple ≠ violet. They don't even look the same. You won't see violet on a computer screen because it's a higher frequency than what blue LEDs produce. You won't see it on the output of consumer-grade printers for similar reasons regarding the color of the ink. The easiest way to see actual true violet is to pass sunlight through a prism onto a white surface. Purple on the other hand is a mixture of red and blue frequencies that stimulate both kinds of receptors in your eyes. It looks like a reddish blue that can't be produced by any one frequency of light. True violet looks like a deep, deep blue without any red tint.
