If crayons could complain, what would they say?  In this book, Duncan finds out.  In a series of letters written to Duncan by each color, he finds out that most of them aren’t too happy with how he is using them.  Very, very clever idea!  Each letter is written rather humorously and you can hear the ‘voice’ of the crayon.  Some colors complain that they aren’t used enough, or they are used too much.  Some just don’t like their color.  It forces one to really think about how we use color.  At the end of the story, Duncan colors a beautiful picture, using all the colors in a non-traditional way.  All ages will get a kick out of this book.
