Originally written in 1973, but not published until after the doctor's death, this book explores colour and moods, and is quite different from the familiar Seuss style. Full colour. Readership level: 5 - 7 years 'You'd be surprised how many ways I change on different coloured days.'Maybe on some days you feel sort of brown, like a bear; you feel slow and low, low down. But then comes a yellow day and wheeeeeeeee! you feel like a busy, buzzy bee. Dr. Seuss takes the reader on a journey through many different moods in this vibrant and highly original book.
