I first saw this idea over a year ago over at Sassy Monkey Reads. She'd posted an amazing picture of a weekend project she'd just completed (click to go see for yourself). I was delighted with the end result, but never really considered a similar undertaking.
It seemed waaaay too contrary my Type A personality way of organizing and arranging things...
But it looked so pretty!
No, I told myself, I'd never be able to find anything...
My kids would wreck it...
But... soooo pretty!
Then, not surprising, I did nothing. But I never forgot that picture. And last week when I decided to do a search on Flickr for "rainbow books", the same smile spread across my face. As I spent the better part of 30 minutes clicking through image after image of books arranged by colour, it became impossible to resist. I mean, just look at these:

1. Camdyn's colorful bookshelf!, 2. New library, 3. Rainbow, 4. Bedroom book rainbow, 5. Rainbow of Books (Explore #93)., 6. Rainbow Books
Amazing, right? So. Much. Better. So much better than books arranged by author or subject or simply by height *yawn*. I think every room can be improved with the presence of a rainbow. The colours are so bright and fun and cheerful. Dewey Decimal who??
At first, I wasn't sure we had enough colourful books to even make a rainbow. There was a lot of white and pale yellow, not much pink or purple (not surprising) and lots of blue (also not surprising). What did surprise me is that we only have one (one!) orange book*. I mean really orange. ORANGE IS MY FAVOURITE COLOUR.
Speaking of colour, sorry about these pictures... A good reminder before my photo session this afternoon TO ALWAYS CHECK MY SETTINGS BEFORE SHOOTING. Ah well, these pictures will do for now. I'll take some more after we paint the walls grey and the shelf itself white. The antique dresser next to the shelf will also be getting a fresh coat of paint.
(Yes, that lamp shade is broken (thanks boys). And yes, those are knitting needles** sticking up out of those lovely alabaster... vases? jars? candle holders?... lovely nonetheless. Peter's parents bring them to us from Egypt.)

So. What do you think? Peter thinks I'm a bit crazy, but thankfully he's used to it/me by now. I happen to love it. I smile every time I look at the bookshelf (and can't wait to tackle the big shelf in our bedroom and the two full shelves in the boys room).
* It's George Orwell's Animal Farm. That tiny one right in the middle of the top shelf, between Ewan McGregor's Long Way Down and Ayittey's Africa in Chaos.
** I taught myself to knit over Lent! I've actually made some things too! Another post I haven't gotten around to writing yet...
(I'm working on a page to show where this post is linked to. I'll be back! Promise! My kids need lunch now though... how annoying. *wink*)
