Research book part 2

As I reed the Guy Deutscher's book "Through the Language Glass: How the world looks different in other languages", he talks about differential of color and how it is said between nations. For example, in our English language, if a person sees blue, he just says "blue". But in other languages, concept of blue can change. In the Russian language, we have different color of blue, like navy blue, dark blue, light blue or baby blue.
