Conspiracy theory nuttersI keep getting collared by a bloke who says that the war in Afghanistan is a cover for our Illuminati Freemason Shapeshifting Lizard masters to corner the market in mind-bending drugs. "It's true," he says, "I heard it on TalkSport". Tell us your stories of encounters with tinfoil hatters.
Thanks to Davros' Granddad

Actually ...... the electromagnetic spectrum and the mathematics of different wavelengths of light say differently.

Not at all.The wavelength is obviously the same for everyone. But what the brain does with it, and how it "feels" to see light of a certain wavelength, might change from person to person. What counts is that we all agree that grass is green, the sky is blue, and so on. We diagnose colourblindness only when the language doesn't fit.
It's a fairly trivial point, though.

the key point is thatthere is nothing 'green' about the neural signal from the photoreceptor to the brain, its an electrical/chemical signal, the conscious sensation of 'green' is a label that the brain provides. There is speculation that the colour label could be used for other things e.g. dogs may smell in colour.
