What Makes a Rainbow by Betty Ann Schwartz (2003, Hardcover, Mini)

This is a book which introduces both the rainbow and colors. While its intended audience is the toddler -preschool age, it will also enchant older beginner-readers with its bright colors, and real ribbons of color which are added one at a time as each page is turned. Of course the grand finale is the pop up rainbow at the end of the book. Really adorable.
