What is really "green"?
I read many articles but still I do not know what are colours like green:
Is it
-a subjective quality that is made up in human brain, or
-the result of sum of yellow and blue, or
-the presence of radiations of two frequencies in the same source, or just
-the quality of a radiation of a single frequency, as wiki says, in the range between 570 and 590 nm?
Thanks for your help
