The album met mixed to positive reviews upon release. Nash's vocals, lyrics and music direction were lauded. Blue on Blue was criticized mainly because of the songs not being as immediately appealing as the ones released by Sixpence None the Richer. Collaborators on this album are Sixpence bandmate Matt Slocum, and the songwriting/production team of Rick Nowels and Billy Steinberg.
Commercially, the album did not performed well. One of the main reasons for this is the fact that the album remains unknown among the masses due to the lack of promotion and airplay. So far, it managed to reach No. 25 in the BillboardTop Heatseekers charts; however, the bonus track "Blue Sky" reached No. 5 in Japanese pop music Chart due to its frequent airplay and the advertisement of "Toyota Prius" in Japan in 2007.
