APA ships, questions

[richie incident]

In this case, a question arose about applying numbers in colored squares on board for mooring a landing boat. What year was this approved? Was this in WW2?
Haskell-class transports

 

[Yankee Clipper]

Any explanation of the different colors of the number blocks?

I watched the 1956 film "Away All Boats," which was filmed aboard the APA-224 USS Randall. There, I heard commands for boats to dock at "green 6" and "red 2" (I think). I think this is convenient for identification when the numbers are not distinguishable from a long distance or in clear weather.
That's why the question arose whether these signs were in WW2, although I haven't come across any photographs from that time, only post-war ones from the 1950s.

Makes sense, thanks.

After two ad-hoc invasions that fortunately met slight resistance on the beaches (Guadalcanal was bitterly resisted only after the successful landing and North Africa against French forces) the US Navy and Marines appear to have tackled this problem with 1940’s industrial principals. For example the amazing variety of landing craft produced on short notice by American Industry. It therefore, would follow that aboard the attack transports systems were developed so the landing craft crews could land the right guys at the right places on the beach. These numbers would have served that purpose.

Mr. Pellett, in order to plan the creation of a model ship of the APA for WW2, do you know the time when the mooring markings for boats were applied to the side of the APA`s?
