My family has 5 boys and they ALL look exactly alike... and exactly like their father. The whole family is blonde.

If you want to have smart children and want them to go to college:

In one family I have 2 children and they look just like their parents. Its funny because both parents have black hair and big brown eyes. She is the second generation mother in that house and her daughter look just like her and her sisters did growing up.

I wanted to chip in on the "people doing things you can't stand" thing: maybe this will sound cruel, but I freely use the red hand when they do things I really don't like - for example, banging the dishes, drawing on the walls etc - and in turn use the green hand to cultivate activities that I think are nice. One thing I've found: if you set them on a new activity, for example, parents working, use the green hand twice if you want them to like that activity and do it on their own. They WILL start favoring that activity. Also, if you use the green hand 3 times in a row, they will get upset and tell you to stop nagging of course, don't praise them on EVERYTHING... then they won't know what to do :P But I've found this really works for me.
