Photo Shop collage question
Hope this isn't too far OT -
I'm making a collage of several (dog) photos. I know how to do that, except that I don't know how to make the background (the New Canvas) any color other than black. I'm sure it's dead-simple easy to do, but I haven't figured it out and I'm not finding the answer as I search the Adobe help files.
Can someone point the way to making that New canvas black?
