Idézet: MartinBV - 2011.06.06. 21:09:10 Which is the 3rd colour of the rainbow?
orange
red
yellow <- marked as correct
green
We have been through this before, the rainbow is a continuous spectrum of colors from red to violet (it actually goes further in both directions, but that's invisible) so there is no 3rd colour.
I am puzzled though because if you ask the colors of the rainbow, you will get an answer of 7 colors although in fact is a spectrum as you say. So the question is not wrong but neither right. It depends on the detail you examine it with. Like we say the sun rises, although in reality it does not move.
