I'm not making skins anymore, mate. The ones I've released recently are either old ones I made last year or quite older ones that needed an update to the latest patch. As of right now, I can't really put as much time and effort on my skins as before, and I refuse to lower quality for the sake of saving time.

However, here's a good image you can use to make your reg colour:
