A couple of gorgeous books we have in our home library that fit perfectly into our rainbow theme. Colour Me Happy by Shen Roddie and Ben Cort: A gorgeous book about exploring emotions through colours with a beautiful rainbow ending. Planting a Rainbow by Lois Ehlert: A story about watching the rainbow of colours grow in the garden through the seasons. Each page in the book represents a colour in the rainbow. Visit you local library to find more books to fit with the rainbow theme!
