Organizing the Master Closet

There are so many ways to organize a master bedroom closet. By color, clothing items, or just stuff it in there and so many more! What is your favorite? I like to hang my clothes by color, solids then pattern. Short sleeve, then long sleeve with sweaters together. It makes it SO much easier to get dressed because I don't have to search for items. HOWEVER, every once in a while it needs to be reorganized. I have also been considering painting or wallpapering the closet... your thoughts? {the first picture is the after and the second picture is the before}I reorganized it and could not really tell by the picture which was which. I guess it wasn't that bad!
