So I wanted to revive this thread to those who are skeptical about coloring the stitching of their interior. I used a simple paint marker and all of the work took 30 minutes or so. Just simply go down the stitching a few inches and wipe off. I did the whole interior (door panels, seats, center console, etc.). The pictures seem like the color is faded but its much more red than it looks. Excuse the filthiness.

Here you go!
