The unisex Blake, which indeed has two conflicting meanings, has a briskly efficient image when used for a girl. 
 Though in the eighties it was seen very much as a <a href="https://nameberry.com/boys-names">boys’ name</a>, epitomized by the character of Blake Carrington, the silver-haired, powerful patriarch of the TV soap Dynasty, these days it's more apt to be associated with Blake Lively, the attractive lead of the Gossip Girl series and the film Sisterhood of the Traveling Pants.

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.
 Blue is the heroine of the trendy Marisha Pessl novel Special Topics in Calamity Physics.

Blythe originated as a nickname for an upbeat person, coming from the Old English word bliðe, meaning "merry" or "cheerful." Today the homophone blithe shares the same meaning. Blythe was eventually adapted to a surname before it became a feminine given name.
 
Blythe embodies a cheerful, carefree spirit and could be the next Blair/Blaine/Blake/Brett/Britt, with the advantage that it's clearly pink. It joins other other light-hearted names for girls: Felicity, Hilary.
 Blythe is the middle name of Drew Barrymore—in her case a surname from her rich theatrical history.
 The title of the memorable Noel Coward play Blithe Spirit is taken from Shelley's poetic line, "Hail to thee, blithe Spirit"—a nice tribute to a baby Blythe.

Clementine is a Nameberry favorite that broke back into the US Top 1000 in 2014 after more than half a century off the list. 
 A female variation of the more-unusual Clement, Clementine's meaning suggests peace and happiness, a lovely image. Other girls' names with similar meanings include Beatrice, Felicity, Hilary, Arcadia, Irina, and Mercy.
 If "Oh, My Darlin'" still rings too loudly in your ears, consider pronouncing Clementine as Clementeen—or even using Clementina, which rhymes with Christina. Stylish Claudia Schiffer chose Clementine for her daughter, as did Ethan Hawke and Rachel Griffiths. 
 Kate Winslet played a character named Clementine in Eternal Sunshine of the Spotless Mind. And for a kid reference—there's a Muppet named Clementine.

Even among the range of blue names on the current baby naming palette -- Blue itself, Azure, Cerulean, Teal, Aqua, Cyan, Indigo -- Cobalt remains the most unusual, not to mention the most masculine.

Cobalt

Cyane is a mythological Sicilian nymph who lived in a pool and whose name is an intriguing twist on the color name trend.

Lovely entry into the tree name genre, joining Juniper, Oak, and Willow.

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. 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.
 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.

This body of water runs deep; the best of a group of new possibilities that includes Bay, Ocean, River, and the more established Brook. It has received attention via the actress Lake Bell. Lake would make a particularly cool and refreshing middle name, as Gisele Bundchen and Tom Brady did for daughter Vivian.
 Lake is also a fairly common surname, represented by 1940's blonde femme fatale Veronica (born Constance Ockelman), actress/talk show host Ricki and Emerson, Lake & Palmer bassist Greg.

Lake

Lark is getting some new and well-deserved attention as a post-Robin and Raven bird name. Although it was first recorded as a name in the 1830's, it has never appeared on the Social Security list.
 'The Lark' was used as a nickname for Cosette in Les Miserables; Lark Voorhees was a star of Saved by the Bell, and Jennifer Connelly and Paul Bettany used Lark as the middle name of their daughter Agnes.
 
The expression "happy as a lark" gives this songbird name a cheery image, as well as a 'lark' being a synonym for a merry time..
 Larkin is a pretty extension, as is Skylark, which is rich in cultural associations: there's the Percy Bysshe Shelley ode To a Skylark and the jazz classic Skylark written by Johnny Mercer and Hoagy Carmichael..

Magnolia, a sweet-smelling Southern belle of a name made famous via the iconic Edna Ferber novel and musical Showboat, is one of the latest wave of botanical names, along with unexpected blossoms Azalea and Zinnia. It is named for French botanist Pierre Magnol.
 Magnolia has been chosen for his daughter by Adrian Young of No Doubt—which happens to be a fabulous baby-naming consortium as well as a great musical group.
 In Showboat, the Magnolia character goes by nicknames Noa, Nollie, and Maggie.
 Magnolia charted on the popularity list almost every year from 1880 to 1940, topping at Number 420 in 1909—but it's now making a comeback.
 Magnolia Breeland is a character on the TV show Hart of Dixie, who happens to have a sister named Lemon and a father named Brick.
 Maminydjama Magnolia Maymuru is an Indigenous Australian model.

This Old Testament female name has been one of the most popular <a href="https://nameberry.com/girls-names">girls’ names</a> in Israel over the last decade. Also highly popular in Spain, Portugal and the Netherlands, and a new entrant to the US Top 1000, it may be misunderstood here as an attempt to streamline and feminize the more familiar Noah – although it's a separate name with a separate derivation.

 Now for the confusing bit... There is a female figure in the Old Testament named Noa or Noah, whose name derives from the Hebrew No'ah, meaning "motion". The popular Biblical male name Noah (sometimes spelled as the streamlined Noa) is derived from a different Hebrew name: Noach "rest, repose" – although confusingly they are often written the same in English. 

 Noa is the modern Hebrew spelling of the female name, but it is also found as a variant spelling of the male name Noah – popular in countries including France, Croatia and Bosnia and Herzegovina. 

 Complex backstory notwithstanding, Noa's rise to the charts indicates increased interest in this sleek moniker.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four <a href="https://nameberry.com/search/girls-names/o">girl names starting with O</a> on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen. 
Olive has positive associations to the olive branch as a symbol of peace and the ancient olive wreath that celebrated success.
 Olive was the name of the adorable Abigail Breslin character in the popular movie Little Miss Sunshine. Olive Chancellor is a major character in Henry James's The Bostonians and Olive Kitteridge is a Pulitzer Prize-winning Elizabeth Strout novel that was adapted into a TV miniseries in 2014. Kids might be familiar with Olive the Other Reindeer.
 Olive came into fashion at the end of the nineteenth century along with other botanical names, when it had a run in the Top 100.

Orchid is a hothouse bloom that has not been plucked by many modern baby namers — yet. In the language of flowers, orchids symbolize love, beauty, and sophistication. 
 In a 1926 silent comedy, femme fatale Gloria Swanson played a burlesque chorus girl named Orchid Murphy.

Peridot is the gem of the month of August, a vibrant green mineral, said to be good for helping people put the past behind them, and an interesting, undiscovered jewel name. It was regarded in ancient times as the symbol of the sun.
 Peridots figure in the mythologies of several cultures, including the ancient Egyptian and Roman. They are highly valued in Hawaii, where it is believed that they are the tears of the volcano goddess Pele. 
 If you want a truly original gem name, you might consider this instead of Opal or Ruby.

Persephone is the esoteric name of the Greek mythological daughter of Zeus by Demeter, the queen of the harvest. After she was kidnapped by Hades to be Queen of the Underworld, it was decreed by Zeus that she would spend six months of the year with her mother, allowing crops to grow, and six in mourning, thus accounting for the seasons.
 Despite the mixed message of her mythological past, Persephone has a light and lyrical aura, and pleasant associations with springtime and the harvest; she was also goddess of spring growth. Persephone was seen in the Matrix movies, played by Monica Bellucci, and could make an interesting replacement for the overused Stephanie.
 Persephone's meaning is in dispute: While some sources give it as the worrisome "bringing death," others indicate that's it's associated with dark blue and with speaking. Persephone was called Kore in childhood; in Roman mythology, she is Proserpina.
 Persephone is popular on Nameberry, ranking in the Top 100.

British-born novelist Plum Sykes has taken this rich, fruity name out of the produce section and put it into the baby name basket. It's more appealing than Apple, more presentable than Peaches. The French equivalent, Prune, is very fashionable there but would not fly with English speakers.
 Plum Sykes was born Victoria, and her nickname derived from the variety of fruit called the Victoria Plum.
 Plum makes an appealing middle name choice--Moon Unit Zappa used it as such for her daughter Matilda. The color of the fruit makes it one of the appropriately amethyst-hued <a href="https://nameberry.com//list/614/names-for-aquarius-babies">names for Aquarius babies</a>.

There's definitely a cold front of <a href="https://nameberry.com/list/89/winter-baby-names">names for winter babies</a> moving in, with Summer, Spring and Autumn giving way to Winter--plus North, January, Frost--and Snow. This name feels brisk, fresh, pure, evocative -- and magical. A haunting middle name choice. 
 Rare as a first name, there have been several notable surnamed Snows--including singers Hank and Phoebe, and scientist/novelist C.P. And then there's the dreamy Jon Snow in Game of Thrones.

Snow

With related choices such as Lark and Phoenix gaining popularity, why not Sparrow? Though it's usually thought of as a female name, Nicole Richie and Joel Madden chose it for their son.

Sparrow

Unusual choice that was the original name of children's illustrator Tasha Tudor, but is an interesting elaboration of Star, taking it into avian territory. 

Starling

This name of both a grayish-greenish-blue color and a kind of wild duck can be used for both boys and girls. 

Teal

Teal is one of the prettiest and most straightforward of the new color names -- an ideal middle name choice. 

The girls have dibs on Spring, Summer, and Autumn, leaving this name evocative of snowy landscapes as the one possible seasonal choice for boys. And naturally, it's one of the most obvious <a href="https://nameberry.com/list/89/winter-baby-names">names for winter babies</a>.

Wren, a lilting songbird name, could be the next Robin. Wren entered the Top 1000 for the first time in 2012 and is among the new wave of popular <a href="https://nameberry.com/baby-names/501/english-names-for-girls">English names for girls</a>.
 Wren makes a particularly pleasing middle name choice, as does her newly discovered cousin Lark. But it's more popular as a middle name than you might think, the quirkier cousin of Rose.
 This petite bird was regarded in Ireland as the "magician of the birds" and the Druids considered it a bird of prophecy. Thanks to an early fable, it has also been known as King of the Birds.
 For architects there's the link to the great Sir Christopher Wren, the celebrated eighteenth century designer of London's St. Paul's Cathedral.
