eli5 What makes the color green, green?

616 views

Hello all,
I am working on a project that requires me to identify what colors are green. This seems easy enough but I am working with color codes and don’t know where certain colors start and/or cut off.
I am working with RGB and a color can appear completely red with a value of 1 for Green but not appear green at all. Would this still be called green?

There is no hard and fast rule; colour labels are applied to light of a range of wavelengths. So green is typically between 495-570nm. Some languages don’t have a specific word for green, so that all might fall under one term with blue, and some will break that part of the spectrum into yellow-green, green, blue-green etc.
