That’s the normal rare Noble body. Not one of the variants.
You can’t go wrong with a dark blue, with a yellow highlight. It’s a bit common, but Dark Grey armor with the highlight of your choice doesn’t look bad either.
I dunno, which colours do you like? There’s no right or wrong answer here, just go with what looks good to you.
I personally use the black (or dark grey, whatever it’s called) simply to have a black undersuit. I can’t stand having a coloured one.
I just go with the classic Green + Gold visor.
