Forum:Questions about editing on wikis

Hi, I'm fairly new here, and I've just gotten around to start editing my profile page or whatever it's called. I want to post my entire weapon collection there, but I want it to look nice. Specifically, I want to be able to change the color of the text to match the rarity color of the gun, and other such things. Is this possible? I've seen colored text in this wiki (like the red text of the legendary weapons) but I dont see the option to change the color of the text when I edit a page. Is it extra code that I need to type in?
