Maybe an option to change interior colors I game?

I have an idea where people could make their interiors in there cars any color they want, like they could do in real life, like for example, pink. With this option, someone could take the covet make it completely pink inside and out, and it would become "Pink Puss" (look it up, you will get something along the lines of "Ohio's oldest ricer"
But this option could go in the color menu in the car parts config

 

you already can choose between a few colors in the parts-menu.

 

Some cars in-game do have a few selectable interior colours.
If you're talking about being able to select any colour you want, then that's not possible currently.

 

Although it is likely to be possible in a future update however
