Pink-out the lower side edge (below doors), the door handles, mirrors, rear above the plate, in the horizontal bumper cut-out, and hatch wing center (NOT edges/ends)-if you have one.
That would "pop" nicely.
Some silver, black, or gray accent graphic in the middle of the roof might look neat. Maybe, gray double stripes (10-11" wide lined up to the roof bumps)?
If I hadn't done the Saltire on my roof, I would have done a double stripe in white, as an armoured skunk (my B is also silver)!
