The book was a children’s book from the 1980’s that had something to do with rainbows and dinosaurs. Each page had a different dinosaur of a different color. The text would be something like the “the green dinosaur play in the grass”. I’m not sure if that is an actual quote from the book but it gives an example. The only sentence I do remember is “the black dinosaur waits for the dawn.” I learned to read by memorizing this book and then later recognizing the words and letters. I would like to find this book for my toddler son. Please let me know if you can help.
