Alienware Aurora Case lights changing when running games

Hi all,

Firstly sorry if this is in the wrong place, please move it if that is the case.

I got my Alienware Aurora delivered yesterday and booted up battlefield 3 to try it out. Now my case lights are the auqa colour ( so light bluey green) but when in bf3 they changed to orange and sometimes white, i also found it would go red if I was getting shot.

My first thought was there was an issue with temperature and it was their way of telling me about it, but after watching it for a bit longer it seem to respond to things happening in game. 

Does anyone know why the lights change the way they do? should I be worried?

If there is a way to control this that would also be great to know.

Thanks
