Some Wranglers came with wider painted fender flares in body color, black, or gray. (Saharas, Rubicons, and some special edition Wranglers).
Most all the rest are just black plastic flares that fade and turn gray.
A lot of folks on here use Krylon Fusion satin black spray paint for plastics. I took their advice and painted my flares. They looked great, and the rear flares (all I have left now) still look pretty good 4+ years after painting.
I just used Back to Black. Good result and it maintained the texture.
This treatment only lasts a month or so. OP, don't do this.
I did mine with "back-to-black when I first got my Jeep. Then after getting black stains on my jeans anytime I brushed against the flares, they were back to faded by the end of the month.

If you plan on actually doing some Four Wheeling, your fender extensions are gonna get pretty scratched up. So, you could put out a ten spot for the higher priced fix that won't last any longer or look any better after a few go-arounds with the "Great Outdoors," or you could do what the rest of us do, Krylon Bumper and Trim, spray on hides a whole lot of those times that things just don't go right, and it's cheaper too!
