All I wanna do is change my background color I feel like anything else would be too complicated for me LOL. Sooooo how do I do that?

Are you working on a user profile, or pet profile?

my profile

The easiest way is go to Edit Profile > Add Section > Profile widget. Click edit on the Profile widget, and change the scheme.

If you want a custom colour, set scheme to none, paste this with your hex code instead of "" <style> body {background-color: ;} </style>
