For less than $10, at your local hardware store, Plasti spray paint is your best bet. They come with white, black, red, yellow, and blue. After it is completely dry, it still give you rubbery like surface and extra protection than original cable, and if you don't like it, just peel it off.
The only problem is it will make it thicker, so if you route it through any AW stand, it might not fit well.
Make sure cover anything you don't want to paint. I would give it a good 2-3 coats at warm temp weather.
Personally, I would not get 3rd party AW charging cable, yet, inductive charge is a little tricky.
