Rocky, try this thread first for pictures. This may help you narrow down your choices, though all you have left if you do not want black are Adrenaline Red (an override color costing you $590), light gray, Brownstone and Kalahairi.
There are separate threads for each of those interior colors, and to get there, go to the "photos and videos section," then type in the following words in the search box, e.g. official Brownstone thread, official Kalahairi thread, official gray interior thread, and official Adrenaline Red thread. Note that while the official GM name for the gray interior is "Medium Ashen Gray," it is a light, light gray.
If you are looking for others' opinions, we are kind here, but not bashful. My opinion would be to consider gray (unless you are using the car for a daily driver) and Kalahairi. Good luck in making your choice.
Had a c5 z06 beautiful millennium yellow nice black interior, traded for a c6 z06 beautiful velocity yellow black interior, traded for a c7 z51 beautiful velocity yellow drop dead gorgeous adrenaline red interior. That's what I'm talking about!
I love VY and I love Kalahari, so I crossed my fingers and that's what I ordered. I am very pleased as I think they go together very well, I get many positive comments. I also think Brownstone would do well.
