Newton gave it: red, orange, yellow, green, blue, indigo and violet
Imho, indigo and violet are the same thing (at least very close), and cyan is missing, so red, orange, yellow, green, cyan, blue, violet would have made more sense
But of course it's indeed quite possible the language shifted and it made sense in Newton's time
- belinder 7y agoImo cyan and blue are a lot closer than indigo and violet
- Aardwolf 7y agoTo me cyan looks blue-green, really in the middle but also significantly lighter than blue, while indigo and violet both look purple-like I'm not a native English speaker though, and as far as I know neither cyan nor indigo are commonly used in standard everyday language, but more in their own niches (printing, clothing, ...)
- kazinator 7y agoThe reason there is violet, by the way, is that the eye's red receptors weakly respond in that range, causing a perception of red to creep into the blue.
