Inetrior colour need help

HEy all, I am building a 06 mustang for my wife. I am painting it pepper gray metallic, which is elanors colour. I need some suggestions for interior colours.any help would be appreciated. I want to go with black and red but she isnt to keen on it.

Black and charcoal grey?

What colors is your wife keen on?

The Rousch 'Stang' I saw had a black interior. I've seen the red in a silver vert. as well. Black and tan is the only other choice I can think of that would be a 'normal' choice.
