Coloring wall problems

I'm a new user and have what I consider a newbie question. I have searched, but can't find any solution. My questions are:
1. Why is the half of the end of the short wall green (Nr 1)?
2. What is best practice to color the end of the short wall in one color?
3. Why is the top of some of the walls colored. (Eg. Nr 2)
