A while ago, I rendered some custom graphics for PlayStation 4's Dual Shock 4. All were based on famous racing liveries.

I've decided to get custom skins made. I've chosen my first one, Martini on white:

I can't choose what to get on the second controller. BMW ///M stripes (or chequers) would look awesome, but the color scheme is too similar to the Martini one.

Any better ideas?
