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.

Lennox is one of the new breed of surname names on the rise as a Scottish name for girls as well as boys.

Blue suddenly came into the spotlight, as the unusual color name chosen by Beyonce and Jay-Z for their baby girl Blue Ivy.

Dave 'The Edge' Evans named his daughter Blue Angel back in 1989.

This number name first came to public attention when Erykah Badu and Andre 3000 chose if for their son, Seven Sirius Benjamin, born in 1997.

A simple, unusual word name with an evocative meaning, Ever feels similar enough to Eva, Evelyn, and Everly that it shifts easily into name territory.
