Black rear shell skin

[willydimes]

I was really hoping that the 6/6 plus would have a true black rear shell but unfortunately not. I do have a black apple case but I also like to use it without the case. Are there any legitimate options to give a black appearance on the rear shell that doesn't look crappy without adding bulk to it?

Sadly Im in dental school and not a billionaire who could afford one of those Feld and Volk custom jobs although it would be awesome
