 Also, I understand that certain animals can see ultraviolet and infrared. Would this mean the visual spectrum will be larger for them and therefore something that appears orange would appear red or yellow to them? For example, would a bee or a wasp see violet as blue and blue as green based on the fact their spectrum is fresh? Would it be possible that the spectrum is flipped so that blue is red and red is blue? One last thing. If there are no green stars out there, wouldn't the discovery of a green star prove that it's manufactured by alien life? Thank you for your time.
