Are the images of Jesus drawn with blond hair and blue eyes correct? Lately I heard that, as an inhabitant of ancient Israel, it is more likely that Jesus had dark skin and probably had hair that was a little curly. 

Why is it that illustrations always show him with blond hair and blue eyes, and how did he really look? Also, I know that, for believing in him, his appearance doesn't really matter, but it still interests me.
There was an interesting show years ago to find out what Jesus looked like, and he would be darker skinned than he is depicted for a couple of obvious reasons, one being that due to his origin from a group that lived in a desert-like region, and the fact that he was a carpenter meant that he worked outside a great deal, so he would be tanned.

But, the fact that we show Jesus as white is due to our familiarity with it, I remember visiting a black friend when I was a child and he had pictures of a black Jesus and a black Santa, and that struck me as wrong (I was probably 7 at the time).
