<*stomping feet*> I don't want just black! I want various colours. Green for unexposed (why can't I change the font colour here!?). Red for exposed. Blue for dubious stuff. Yellow for dud/bad loads. Black for B&W work...but now I need a bigger camera bag to hold the growing number of reborn M&M containers...
Solution: colored labels. Or those colored round sticky dots that can go on the cap.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
