Question re. 20thFG P-51 markings please. Was it O/D above the nose marking or Black?

From a picture of "My Rosie" (P-51D 44-14692) of the 77th Squadron, 20th FG its definitely olive darb.

Found in "Aces and Pilots of the US 8th/9th Air Force".

Thanks Kodoss, that image is similar to the one I saw but I also have a shot of about 15 P-51's of the 20th FG and there is a clear change in colour from the side of the cowling to the top of the cowling making me think it was O/D, but I see some profiles online which show they were or could have been Black, however I have yet to see a picture that indicates this is correct, so I'll stick with O/D.

I also think that the internet colours are inaccurate on my screen as the Dark Blue appearance must I think be Black.

Finally for the markings:

55th FS (Triangle on Rudder) letters example KI - C

77th FS (Circle on Rudder) letters example LC-F

79th FS (Square on Rudder) letters example MC-R
