Love the frozen VO paint job. IMHO, VO is a hard color to match in terms of having any other colored accents( stickers/ calipers / rims etc) apart from black..
Maybe you can try a subtle approach. Use a gloss transparent sticker to make the decals appear gloss vo on a matte vo surface.
I've done this on my matte gray car b4 and use gloss film for the decals. Subtle without having to introduce another color
.
Try to get some pics up later. Nice car BTW.
Cheers!
