Have you ever organized your books by the color of the dust jacket?

Have you ever done anything else that might be considered strange by others in order to organize your things?

I was sitting in my study, having just read my son his bedtime story, and was looking at my book shelves. I noticed that in one section, almost all the books were blue, and this idea came to me. I’m sure there are some artistic types out there who probably do this. I would dearly like to see a sort of rainbow arching across my book shelves. I wonder if people would notice?

So…. Have you?
