What color will the inside of my book's cover be?

Your inside front and back cover cover will be white if you're ordering a Classic Custom book. 

For the Seamless Lay-flat or Premium Mini books, the  book style, the inside front will be white.  The inside back will be either white with a Picaboo logo (for a book with an even number of pages) or the inside back cover will be your last odd page, if your book has an odd number of pages.
