Offensive Interior White Stitching

[Euroskank]

I utterly adore my new Japanese vehicle, however, I absolutely detest the interior's white stitching contrasting on the car's black NuLuxe. It looks very tacky. 

Has anyone attempted to colour theirs in with a pen? Fortunately, this won't be my first colour-change project; I changed the colour of my Thule cabin bag's zips from hideous teal blue to a less offensive black...much more in keeping with the main colour of the bag. 

In hindsight I should probably have opted for the classy rose colour which I strongly contemplated, but a YT vid said sunlight through the tinted sunroof had given that particular vehicle's interior (poss. tan leather) a strange hue.

And just like that, all my troubles don't seem too bad after all

How about trying a black Sharpie permanent marker on the offending stitching.Try an inconspicuous area first to see if the ink is really permanent.Or simply just ignore it,after all,if it was that offensive,you wouldn't have bought the car in the first place.
