White masking tape and a black sharpie. I can read those suckers on the shelf from halfway across the room. If I'm really ambitious I'll use my printer to make a label on white computer paper, then use that clear 2" packing tape to stick it to the box. That stuff sticks to anything!
I guess silver on black would work, but black on white is more visable from a distance.

I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
