Longest color wave lengths?

There is no longest wave-length for light. It can be infinitely long (just as light waves could be infinitely short). The longest visible light that humans can see is about 750 nanometers long, which is 0.00075 of a millimeter. This color would be a shade of red. Some other animals and insects can see slightly longer wavelengths, and many can not even see what we can.
