Rafael, Arlo or Luca?

[SapphosRock]

Which is your favourite?

Rafael (I prefer the spelling Raphael) is my favourite and I don’t like the other two.

Rafael is gorgeous and my easy favourite of your list. Such a cool name, and I love nickname Raffy.
Luca is okay.
Dislike Arlo.
I feel both Luca and Arlo also suffer from being over-used around me.

Do angels have a particular hair colour?

Arlo is very popular where I live (south), there's about 6 at our nursery, not sure if that may be offputting for you?
