Baby name help

We have a boy name picked bit struggling with girls! 
Some we like are Colette, Ella and Lila. 
Please vote and comment. 
I want a feminine and sophisticated name name that compliments Eva, our first daughter. 
Concerns with Colette - I say it cah-lette. I like traditional spellings or else I'd do Collette. ?? 
Concerns with Ella - popularity
Concerns with Lila - pronunciation. It's ly-la but u like the traditional spelling.
 We have issues all the time with Eva being called "Ava" and id rather not have another pronounuaton problem!
