Black would look just fine on a graphite grey. At least in my opinion. I don't think the reflective would look as good on GG...but a nice dark black would.

dont know if you can tell but this is limo tint or 5% but i've just received my 5th ticket for tint so i decided to go leagal for texas which is 25% in the front

go for 20% (or 80%) i think i am
