Matching socks detector

Sometimes people like me will grab any pair of socks to wear even if they are of different color. I wish my socks had some kind of tiny wireless beeping device on them that would beep every time I didn't wear a matching pair. It's function can be simple. Every time a sock's matching pair is not within a distance of one meter it would beep. This way it would also help me not to lose socks.
