There is a definite for painting books which this meets, with the added value of an idea behind it. Actually, I cannot feel that children need to learn color through the medium of a book, but perhaps this could be considered as contributing to the sense of related colors, as the primary colors are brought together at the end in the rainbow. Successively each color is introduced with illustrative objects and followed by a double spread page to be crayoned or painted in that color. A certain amount of adult direction will be necessary if the child is to be kept to the original idea. Cloth bound book, but it gives an impression of being cheaply made.
