First new Audi Blacks...

There are actually two new Black shades:

H8H8 Panterschwarz Perleffekt Z9Z

and

3G3G Smaragdschwarz Perleffekt Y9W

Panter is Black as a night with sparkles while Smaragd is black with a hint of green. BTW, I am not fan of any version of Black.

R8 standard BF Red interior...
It is the same shade as on A3 Cabrio leather and it is not bad at all. Just, I will not reccomend it to you since only standard leather color that I like for interior is Black(PL1 or PL3 leather packages). If you want to combine true silver R8(Eis Silver or darker Apollo Silver) there are few potential leather colors from Audi Exclusive offer that will work nicelly:

1.Classic Red(which is almost burgundy in shade)-Classic Red seats and lower door panels, all other leather Black, all stitching Silver, headlining Leather Back, carpet Black, floormats Black with Classic Red piping and Silver stitching, Steering wheel and gearknob Black with Silver stitching

2.Karmin Red(which is brighter then standard BF Red)-Karmin Red seats and lower door panels, all other leather Black, all stitching Silver, headlining Leather Black, carpet Black, floormats Black with Karmin Red piping and silver stitching, Steering wheel and gearkonb Black with Silver stitching

3.Palais Blue(little bit richer then Navy Blue)-Palais Blue complete interior, all stitching Silver, headlining Alcantara Palais Blue, carpet Palais Blue, floormats Palais Blue with Palais Blue piping and Silver stitching, Steering wheel and gearknob Palais Blue with Silver stitching

4.Maroon Brown(nice warm dark brown)-Maroon Brown compete interior, all stitching Back, Headlining Alcantara Maroon Brown, carpet Maroon Brown, floormats Maroon Brown with Back piping and Black stitching, Steering wheel and gearknob Maroon Brown with Black stitching

These are just few examples based on PYD code(Audi Exclusive leather package 2). I speced my car with Qisha's help and currenty working on order finalization with my dealer.

Start with exterior color, then think about interior...
