Dolly wrote her second book for children, "I Am a Rainbow," with illustrator Heather Sheffield, in 2009 on the Putnam imprint. The book teaches children to connect their emotions with colors so they can better express their feelings and emotions. In a Time magazine interview about the project, Dolly said,
“I wanted to write a book that talked about the emotions of children, which is the rainbow. We all have moods. We talk about being blue when we're sad, and being yellow when we're cowards, and when we're mad, we're red. It's really about us all having these colors, and it's O.K. to have them, but it's learning how to deal with them and what to do with them. It's a sweet little book done in rhyme. I hope to write lots and lots of children's books through the years."
“Well, actually, this is catered to little children. We have the Imagination Library, you know, where I give a book a month to every child from the time it's born until it starts kindergarten through my Imagination Library at the Dollywood -- through the Dollywood Foundation at Dollywood. So this little book is called ‘I Am a Rainbow’ and it is about all the different moods of children."
