The advantage of this book for children from 3 to 4 years, is that it is full of adjectives and qualifiers to describe what it feels like to a color (eg "gray raplaplatissant of deception" Pomelo or seen any disappointed before a gray strawberry, "revealing purple bilberry" or seen Pomelo violet lips blueberries).
There are many repetitions, which helps in the memorization: the same color is available in several cliches funny and extravagant. The pictures are very funny, short texts go very well with the images, it makes the children laugh a lot because the situations presented are funny.
Between repetitions and interesting vocabulary and imaginary situations more than funny, children well retain new words.
Very nice discovery for children from 3 years. My great 7 years read with pleasure this book has its little brothers and I hear them laughing and bananer then they now know the book by heart.
I recommend for young children who are discovering and learning the colors.
