I've seen some profiles (ones like mine) have a simple background color, like blue, pink, yellow, green...ect. Does anyone know how to go about getting a code for the background color? I'm not good at all this CSS stuff, so I don't really know how to do this background stuff. Thanks.

Try using this code in your 'about me' section, either above or below your text (make sure to back up your profile/take a screenshot of it before editing in case something goes wrong!);

(There's also this eye dropper extension that I use for chrome, it's very useful if I see a nice colour I like and want to save it or find out what the hex code is. It also has a colour picker so you could use that too!)

Let me know how it goes or if you need anything else! c:

Yay, that's exactly what I wanted! And it worked! Thank you so much for your help, I really appreciate it a lot!! :)

No problem at all! :D
