Nifty, to add to your post.

Trainer a/c were painted yellow to make them more visible. Now why was that done if yellow was not known to be more visible Mirek?

So Mirek, even in the 1930s-1940s yellow was known to be the more visible color. For further proof Mirek, answer me why the British used a yellow stripe on the leading edge of the wing instead of another color?

Now as to the 'Red Baron'. He did not use red to make his a/c more visible but to make it more recognizable. Even the other a/c in his unit used red on their a/c. Great pychological move by him and his Jasta.
