German 7.7cm 'Universal' shell paint colour

[starshell]

Good evening,

Would anyone here have any information as to what colour German First war 7.7cm Universal shells were when issued.

I have vague info suggesting it might be plain Feldgrau, but need to know for sure prior to a restoration of such a shell.
Also, was the shell marked with any stencils, colour bands, etc.
Any info would be much appreciated. Many thanks in advance!

Cheers!

I don't know official color code and RAL.
Seems to be green, feldgrau type.

Thank you.
