Sorry if you're offended but I don't like it at all.
Zowie looks awful, I can just barely tolerate
Zoe. Blue, if it has importance to you (eg. family surname) then it is fine as a mn but it sounds so cutesy next to
Zoe.
Catherine Blue or
Josephine Blue,
Caroline Blue,
Veronica Blue or something along those lines wouldn't be so bad.
Apple is a fruit, and I'm sure you got it from
Gwyneth Paltrow. Apologies if it does have family value.
Livia is fine, but the transition from the "a" at the end to the "a" at Apple does not appeal to me at all, just as I cannot stand the flow of say
Maria Anne or
Joanna Alice.
I think overall, the combos sound like something out of a cartoon comic.
