Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Although most people don't think of it like this, Indigo might also be considered among the most stylish Greek baby names in use today. Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

With Azariah and Azriel in the Top 1000, and Ezra, Josiah, and Isaiah in the Top 100, it makes sense that this lesser known Hebrew choice is being revived in the US.

Theon is a similar name made familiar by the popular series Game of Thrones: Might it and Theron rise in tandem?

Xavian is a masculine name representing a modern variation of Xavier, which itself derives from the Basque place name Etxeberria, meaning 'new house.'
