Blue suddenly came into the spotlight, as the unusual color name chosen by Beyonce and Jay-Z for their baby girl Blue Ivy. Blue is also a starbaby middle name du jour, used for both sexes in different spellings and forms, from John Travolta and Kelly Preston's Ella Bleu to Alicia Silverstone's Bear Blu. Dave 'The Edge' Evans named his daughter Blue Angel back in 1989.

This hyper-rhythmic name has two evocative references. In Greek mythology, she was an island nymph, a daughter of Atlas, who delayed Odysseus from returning home. It is also a genre of West Indian music, originating in Trinidad and Tobago and largely popularized in the States by Harry Belafonte.

Seinfeld's George threatened to name his future child Seven, and then singer Erykah Badu actually did it.

The e-addition takes the name from slightly hippie-ish nature name to the place name of a picturesque island off the coast of Scotland, and for baby namers it's by far the more popular spelling.
