Is Grey rare?

[Redballoon]

The 1st of three new budgies came out of the box today and he is grey with black contrast.
The other two are the same and will be out when they are ready.
Is this colouring rare. I have never seen it before but what I know about budgies would fit in a thimble.

Dad is Purple and mum is sky blue if that helps
