The room that is to be the nursery has a chair rail (nothing fancy, just some molding going around. No wainscoting or anything). Currently we have the room painted with a light beige on top and a darker brown on the bottom. I really want to paint it either white or a very pale off-while.

My question is... Should I paint the bottom differently than the top? Would it look silly to paint both white? If I should paint it different colours on top and bottom, what colours?

Example pictures would be great!

Here is a photo showing the look I am going for :
