Mine was white when I started....in fact, I think only white or natural color was available for the one I ordered
So after trying to die my girth I finally lost it and went down to my neighborhood paint store. I brought a color so they could match it correctly and bought a LATEX stain to die it with. It worked amazing and its so much easier and it does'nt rub off on your flightsuit. So heres what I did
First I get my paint roller liner, stain and girth ready to die.
Then I pour the stain in the liner and begin to soak the girth untill its obsorbed enough stain so theres no white showing. Make sure you force it in with your fingers and hands.
Then once you have it soaked with stain your gona want to ring out the excess stain so it can dry quicker.
Your going to want to hang it up so it can dry but while its hanging get a rag and blot out as much excess stain as you can. Make sure you don't rub it or it will fray, only blot it. Then when thats done just let it air dry for about 24 to 48 hours and your all set. The key thing is to only get latex stain because all other stains will eat and corrode your girth. A pint of stain costs about thirty bucks but it saves you all the headaches that come along with dyes. A pint will dye two girths so if your doing more then that I suggest to buy a gallon. I have only done this in ROTJ color but they can match any color you like.
