xkcd did a perceptual color survey a few years ago: https://blog.xkcd.com/2010/05/03/color-survey-results/ https://blog.xkcd.com/2010/05/03/color-survey-results/ It's population specific to the type of people who read xkcd but it's an interesting starting point if you want higher resolution info on, eg: exactly where people draw the line between "green" and "blue".
