(adsbygoogle = window.adsbygoogle || []).push({}); I don't know how many already know this but here it goes. All you need to do is be in a level 10 or higher clan on elite with a gold clan tag.
Make your clan tag whatever it is supposed to be on elite
Now play one match and it will be gold after the match.
Now anything you change it to will appear in gold.

You can check by going into a lobby, hover over your name and push right. It will pull up you emblem and level. It should show your clan tag on that page and you can see if it's gold or not.

Thanks and I hope that was clear enough to make sense, lol.
