The client had a set of 13 "readers" - books for elementary students and teachers to practice reading - that needed a total refresh. New design, new layout, new content - and each book needed to be cohesive but identifiable.
We used a suite of 13 colors, tints, and shades based on the client's brand to distinguish each of the books, and we applied the exact same styles, formats, and typesettings to every book in the series.
After design was complete, I continued working with the client to publish the books on Amazon's KDP service, ensuring each file adhered to all requirements and making small edits where necessary when the automated system triggered errors.
