I don't get on here much, but had to reply to this one. ( Too many things and not enough time)
I love just about any flavor of ringneck. What can I say - I am a Ringneck Junkie.

I will say thought that my favorite colors are the grey which I have already in the form of an evil nosey bird named Kismet.
I don't know why this is not showing the picture - it was before I edited for the link. GRRR!
But I also really like the Dark Factor Green, the Green split to Blue, the Cobalt and the Violet. I still think that a Normal green in good feather can't be beat for being a gorgeous bird.
Just like my Indy (Normal Green)
You just can't beat that.
This link has the other colors I talked about on the right hand side. The Dark Green is just a darker green. The Green split to Blue is a normal green with a bluish undertone. It looks like a normal green but if you know your ringnecks then you can tell there is something different - the colors seem to just pop a little more than the normal green.

I love my Ringnecks!
