Looking for a case color to go well with DangerZone

[JustCallMeCrash]

Hey guys, I'm building a wooden unibody tented ErgoDox case and I'm trying to decide what color to paint it (it's poplar plywood - staining is out of the question - besides, I'm using Bondo to smooth the joints and fill the grain).
As I'm sure you are aware, the color scheme is  BFU (blue), GSM (gray), YY (yellow), and RAS (red)  ( https://www.massdrop.com/buy/danger-zone-sa-keycap-set  in case you're unfamiliar).  I have 2 yellows and 1 red key in place atm, but could swap one of the yellows for a Navy or Gray... the thing is, I don't love how they look next to black, white, or gray.  I think red or yellow may be a bit much for a whole case, and I imagine I'd be hard-pressed to find the specific RAS or YY hues in a spray paint.
So my conundrum is this:  Does anyone have a suggestion as to what color will look good? 

Thanks in advance. -Crash

I see what you mean about not looking that great against grey but someone posted this on reddit a little while ago, I think it came out pretty well. No idea how it would go on a ErgoDox though

I think some clean stencil work would look really nice with the danger zone set

Dang, that DOES look really good.

Hmm... I'll have to dig into some US Navy iconography.  Thanks for the tips!
