No idea if you give your characters the standard given name, surname format or not, but if you do, Bianca Gainsborough. Otherwise if you're only doing only one name, I'd say Bianca.
For serious though, here's a bunch of names off the top of my head D:... Tiana, Tilly, Terri, Hannah, Maggie, Laura, Abigale/Abby, Annie, Kirstin, Sierra, Katie, Rita, Opal, Pearl, Gem, Crysta/Krysta, Stormy, Sophie/Sophia,
o: ohhh picking names for characters is always so much fun
Shanti , Jade , Luna, Celeste, Seren , Cypress, Shannon , Haven, Kai, Naomi, Sage, Tarin, Terra
