What’s it about?
The story.
The Colour Monster wakes up feeling confused because all his emotions are mixed together. With the help of a small girl, he learns to sort them out: yellow for happiness, blue for sadness, red for anger, black for fear, green for calm and pink for love. Anna Llenas uses collage-style illustration and bold colour associations to make emotions concrete for young children. The book is direct and educational, but the monster character keeps it playful rather than clinical. It has become a staple for nurseries, schools and homes because adults can easily use it to ask children what they are feeling and why. It is an essential social-emotional record: not the most subtle literary picture book, but exceptionally practical, visually memorable and valuable for children who need help naming inner states.

Why it lands
Why they love it.
Why kids love it
The specific use is sorting — a three-year-old gets to literally watch tangled-up feelings become separate, named, coloured things in jars. The book that gives small children their first vocabulary for what's actually going on inside them. Repeats well; works at any age between two and five.
- Being understood finally
- Friendship and belonging
- Transformation
Why parents love it
