I need help chaning my background on AUTO CAD?

Ok I just bought the student version of Auto CAD and as soon as I opened it the background is black and I'm normally use to working with a white background its easier for me to see everything. I was just wondering if anyone knew how to change the background from black to white. I use to know how to do it from my CAD cles but now I forgot. So please someone help me. And I need someone with AUTO CAD experience.
