How do one identify a witch?

witches are not the obvious old ladies that live alone and are really ugly, as if they were then there would not be any old ladies, and i'm sure you granny is not being burned at the stake right now, is she? witches look like normal people, with a few noticable traits. first, witches always have green eyes, always. they are so bright no contacts can alter them. second, their hair is always black, or has a tiny bit of black in it. if you are unshore, try looking at the routes. third, they always wear their necklaces.
