HELP:Model Car Interiors

I am building a Tamiya Skyline R 34 V-Spec II that comes with seats Sparco/Recaro seats, and im painting the seats red with grey flocking in the part between them (in the cushion area) sorry dont know how to explain them! Any ways I am also putting flocking in between the other 2 seats in the back and the floor, what color should I paint the back seats, I was thinking that red would not be a good idea cus there are no sparco back seats, so please, what color do you think I should paint the back seats??

i have seen many cars that have a colored racing seat in the front seats that go and get their back seat coverd with the same color. they either use leather, cloth or neoprene material.
i say match em up if that's the look you want.
I have a friend who drives a mazdaspeed protege and he has recaro's up front and had a neoprene cover made for the back with the exact same black and blue colors in his front seats. Gives it a complete look

i've seen cars with matching back seats all the time. they usually get them recovered and have the name stitched on the seats because they have the same material by sparco.
