Almost forgot, the background is really one composite image I put together in Photoshop from another background I picked up somewhere I can't remember and a black and white version of a color photograph given to me by one of the other club members, Felipe. I just altered the opacity of the image of the cars on top of the checkerboard/gradient (or was it vice/versa?) and then for each page I alter the hue, saturation, and lightness of the color. Simple, no?
