If you have 2 matching feet - then 2 ought to work for you.

Well after grabbing three you will either have 2 blues and a black or 2 blacks and a blue. So you only need to grab three.

However unfortunately now that you know you have this pair of socks it is still pitch black, which means that even though you know you have a pair of socks you don't know which of the three socks you are holding make a pair.

So this has been a pointless exercise. May I suggest that if this sort of problem worries you you pair your socks or install some sort of light in your room.
