You mean like Berlin & Kay's Basic Color Terms? From which I gather that such languages tend to have fewer colour terms overall.

Still, when green and blue share the same basic word, that doesn't mean people can't differentiate specific shades (e.g. "leaf gr/ue" vs "sky gr/ue"). However, it does seem to me that their colour term really means something more ike "all cool/fresh tones".

I gather other languages combine light green with yellow; or light green, yellow, and orange. Which I guess is basically "bright tones", as compared to "hot" or "dark/cold".
