We bought this book for our 1-year-old last Christmas, and she wanted to "read" it all the time. There really are no words other than the name of the color - good for when kids get a little older and are learning how to spell. (My daughter can recognize the words Red, Orange, Yellow, Green, Blue, Indigo, and Purple because of this book.) She now also knows the the colors of the rainbow, in order...including indigo. Yes, indigo is a color in this book between blue and purple - you'd think pink or black or white might have been included, but nope - just indigo. So now my daughter calls anything dark-blue, indigo; this quite impresses her preschool teacher. Overall, fun book.
