Rails static page title and color change

I have one static page whose title, back-ground color and font can be changed by user and changes should persist with users, it means that if I have two user then if first user changes background color to be yellow and second one changes it to orange then if first user again logged in the application, background color should be yellow for him and if second user logged in it should be orange.

How can I proceed with user table and I used devise for authentication.
