Bascially the above - why use these colours? Do these wave lengths travel further or is it just historic? If its just historic, why isnt it changed to make allowances for those who are red/green colour blind?

+ the colors were decided upon by inter-nation safety at sea convention and approved and the info is required to pass maritime licensing requirements.
I like your thought process so that everyone can get it even the color blind, so for the same reasoning we should give drivers licenses to those who are legally blind and airlines pilots should be required to be blindfolded before all take offs and landings. Sorry about the sarcasm but I can't resist.

The colors have to do with right of way. In an open rhodestead, fairway, or seaway, if a vessel is showing red, she has rights. The approaching vessel must give way and not cross ahead of her. Red is stop. If she is showing green, she is the giveway vessel and must avoid crossing ahead of a vessel to her starboard. Green is go. The Lights give basic info between vessels as to aspect and direction, and right of way. White on the masthead indicates a power driven vessel. Number and location of masthead lights indicate size, and nature of work i.e. towing. Stern lights can also indicate nature of work. Two yellow is pushing ahead or alongside, yellow over white is towing. As for color blindness what other colors would you have? Red and Green are most easily diferentiated at night. I am tested annually, and would not feel comfortable meeting another vessel and wondering if he can see the color of my lights due to allowances for color blind people. If you can't see the colors, you shouldn't be operating a vessel at night.

This is historic and the ships captain of today has to past very strict health conditions tests ---color blind people need not apply...the red is the port side and the green is the starboard side of the ship or row-boat the all need to have lights on the nighttime water...

You have a good question, we discovered the problem boating with a brother in law who is red/green colorblind. It is true that it is both historic and that it works at night . Fortunately the buoys are different shaped and the light flash patterns are different for identification also.

Red and Green do not destroy your night vision.

No, it's a national thing. It identifies the aircraft as being a U.S. plane.
