i performed an experiment about this:
i placed one black and one white sheet of equal volume and same material in a room for 15 days.the sheets were paced close to each other side by side and the room was free of all variations.after 15 days,i found much more dust on black sheet(approx. 10 times more)than on white and i also sweeped some dust from both and checked it to eliminate any visual differences when viewing on a black and white surface.so,what is the reason 4 this?
