Tint advice needed for e38 Mojave Brown...

I would really appreciate some advice from some experienced people in this group. I'm going to tint the windows on my e38, which is Mojave Brown. Mojave Brown is something like a mocha-type color, only somewhat metallic. The normal charcoal tint would be okay I guess but I am wondering what anyone has seen that would best complement a color like this? Also, I've found that tints other than charcoal aren't that easy to find and when you do, they aren't cheap, at least here in the Chicago western burbs….

Your help would be appreciated.
