Organizing by Color - Are We Going Too Far?

 
I've talked about organizing by color in several areas: filing, holiday storage, and organizing food by color in the pantry.

Martha Stewart has come up with yet another idea: organize your cutting boards by color. She suggests using yellow for poultry, red for red meat, and green for fruits and vegetables. 

The only time I have organized my cutting boards was when I used to use wooden cutting boards, and I designated one just for onions so the onion flavor wouldn't contaminate other foods. Now that I use plastic cutting boards and wash them in the dishwasher, I don't find it necessary. What do you think of the idea of color coding your cutting boards?

A current decorating trend is to organize your books by color. According to Sophie Kohn's article, organizing books by color brings a calming effect and visual order. Some have even gone to the trouble of covering their books in the same color so they all match.

This idea is a bit intriguing to me, but I think I still prefer organizing my books by category. How do you organize your books?
