Needed input

Okay so we moved almost a year ago and if you have ever been in my home you will know why I am asking this. I want to repaint but how in the world do you choose colors to paint? We just did our bathroom and YES it is purple and the trim is white, I will post pics as soon as I get everything all hung. So I need colors for my and doug's bedroom, the boys room, toy room (I want to put some of the chalkboard paint in there somewhere, my kitchen which is black antiqued cupboards and appliances and is also connected with the living room adn then my hall way upstairs and down, and then the kids bathroom downstairs should I paint it pink or orange and then white trim.
