Colored seat stitching, how dirty?
 

I am going pearl white and having my seats reupholstered black. I was thinking of white stitching for matching accent. For those that have colored stitching, how fast does it start to dirty and turn dingy brownish. This will be a weekend car mainly, so not a ton of wear, but still curious.
Thinking of mid door card in white Alcantara as well, but I'd guess that would dirty and rub bald quickly.
