This is not a colouring book as the blurb on Amazon etc suggest, but rather a book about colours. And a very fine one too.
I really like this because the pictures of full of interest – lots of different objects shown. There are pages with mixed colours too, and the colours include emotions (angry red for example).
It’s a big book for little hands but at least with this you’ll get good usage out of it. Books about colour tend to be incredibly simple and so a toddler will quickly grow out of it. With this you could use it for learning vocab and just sit back and admire the pictures. A great choice for a colour book in my opinion.
