Are there color-matching ProVari batt extension tubes?

[HOPS]

I'm currently saving up cash for a black ProVari mini with green LED's. Estimated date of financial goal is mid-April. I will also be buying a few accessories with the ProVari, and found the Tatroe stuff... I love that their stuff is specifically designed/milled to fit a ProVari, but HATE that they only come in stainless finish. The question I need answered is, are there any color-matched battery extension tubes for the ProVari mini (so that with the OEM extended bottom cap I could use an 18650)? OR, has anyone found any aftermarket paints that exactly match the ProVari black (I used to paint cars so I can do it if necessary, but would rather buy pre-painted as I live in an apartment now)?... Thanks guys!
