I’m stuck for names for a story…I’m looking for one name for a girl with dark hair, and another name for a girl with light hair.
I’d like somewhat other-worldly names, but in a good way - not a weird way!
(E.g. Good = [name]Allegra[/name], [name]Faye[/name], [name]Isolde[/name]
Bad = Skylah, [name]Elvira[/name], Mortitia)
Okay? Thank you so much 
Have fun!
Dark haired: [name]Lark[/name], [name]Valentina[/name], [name]Juliet[/name], [name]Blair[/name], [name]Anastasia[/name]
[name]Light[/name] haired: [name]Isla[/name], [name]Juniper[/name], [name]Allegra[/name], [name]Aviva[/name], [name]Annika[/name]
Sorry some of these aren’t very “other-worldly”, but they fit!
Dark haired girl: [name]Ezra[/name], [name]Nebula[/name] and Lisanna
[name]Light[/name] haried girl: [name]Coraline[/name], [name]Trinity[/name] and [name]Kalypso[/name]/[name]Calypso[/name]
There might be variants in pronunciation and spelling.
How about names that mean “dark” and “light”, respectively? Let’s consult the Super Search …
Light: Lucia (and all Luci- names), Chiara, Eliora/Liora, Naomi/Noemi, Phoebe
Dark: Keira/Kiera (but not Kyra - different origin), Melanie (or variation Melantha), Lilith, Layla/Leila/Laila/…
If I remember correctly, Phoebe and Melanie were among the ideas for sibling / twin names featured in “Beyond Jennifer and Jason” because of their not-too-obvious connection via the contrasting meanings.
[name]Light[/name]-haired: [name]Lux[/name], [name]Dove[/name] ([name]Dovie[/name]), [name]Eleanor[/name], [name]Lumina[/name] (Lumi), [name]Ione[/name], [name]Thea[/name], [name]Marigold[/name] ([name]Goldie[/name]), [name]Aurelia[/name] (could also go by [name]Goldie[/name]), [name]Pearl[/name], [name]Gwendolen[/name]
