@Arkandel for me it's because bright lights can trigger migraines for me and having a big bright white screen glaring angrily at me will do it reliably enough that I have my screen brightness/contrasts turned down so much I can barely see my mouse pointer in some programs. Granted, it's usually not just the light alone, I often need to be hungry and have some stinky jerk with too much perfume nearby, but yeah. White backgrounds are awful.
