EDIT: in general, blue is a pretty fascinating color. yes, many cultures have a somewhat blurry distinction between blue and green. Some others seem to differentiate shades of blue that others don't (i.e. in Russian "голубой" and "синий" refer to distinct colors but in English those would be just shades of blue). I guess there's something about photons in that energy band that messes with perception. https://en.wikipedia.org/wiki/Non-photo_blue
