They are beautiful, Krystal! They are absolutely stunning. The female is a mauve violet opaline, I agree with Aluz. Cobalt would be bluer and more pale, as mentioned. She could even be double factor, actually.
The other is a grey opaline, so you're right
As for names, I have a few suggestions
I think Fiala (means violet in Czech), Cassia, Georgianna, Harper, Saffron (the flower is actually purple) and Zaire are all fitting names for your little purple lady
The grey looks like Tallin, Quintus, Kestrel, Figaro, Kovar or Sterling
Hope this helps, please keep us posted on what you decide! Can't wait to see more of them!
