User-selected custom post background color?

[efblitz]

I saw this on another vBulletin forum (ver 3.7.3) and I was wondering how I would go about adding it to my forum.. On the forum I saw it on, the user selects a color (or background image) to attribute to all of their posts. Here is a screenshot of it: http://img511.imageshack.us/img511/8...background.png

I'm currently running vB 3.8.2. Does anyone know of an available modification or what I would need to change to add something like this?

Thanks in advance.
