The majority of roommates that I've had over the years have all organized their clothes by color. I'm much too lazy to do this, and I've never really cared what it looks like behind my closet doors (ok, or behind my bedroom door). I am however really liking these photos I've seen of books arranged by colors. I've seen so many photos of bookshelves like these, but I can't remember from what sites. So here are a few I just found today. I don't think this look is very functional; it would probably take forever to find a certain book, BUT it looks cool.
Did you know that you could buy books by the foot in whatever color and style you wanted? I guess this is how people actually fill their shelves.
I probably shouldn't buy any more books until I at least get these last purchases out of the box.
