use a cookie to hold the information about what the background colour is and use it if it is available on page load. You can also use localStorage or a database (indexdb or websql) for the same purposes.

If you're using server-side code, you could store the info in a session (or cookie).

No. That's down to you. Research and test. Then come back with what you've tried.
