So what would be the color created by a wavelength of 550nm?
Green or something
Ohhh, I think I get it.
Purple is what you get when you force the visible light spectrum into a wheel, so there'll be something that "connects" blue with red?
If so, is the reason we perceive green as a different color than purple is because we have receptors for that specific wavelength, otherwise both colors would affect our red and blue color receptors similarly?
Essentially, yes. Although violet is a colour, and that does correspond to a wavelength of light. I'm not really sure where violet ends and purple begins.
Looks like this guy has had a crack at explaining the difference, though.
Cool. Thanks
