HG Series Paint Questions

[100550dvr]

Might seem kinda trivial, but what is the correct paint color for the front and rear lights for the late HG Series crawler tractors? I have seen both green and black in color photographs and on crawlers displayed at shows.  I have a number of photos and books for reference, but everything is in black and white. It's dificult to determine exactly what is correct. My best guess is the correct color, from an authentic restoration perspective, is green.

Aslo, should the intake above the hood for the air cleaner be painted black? If so, my assumption is a gloss black.

Thanks for your help.
