They are for sure one of the rarer colors, I got super lucky as a kid and found my purple budgie in our local pet shop. And I named her purple because I was creative. And oh, sounds like you've got quite a bird family there! They definitely really messy eaters!
I want to see your photo, i you have, ahah. Don't worry if not. ;D Ahahah, yup! They are too active when I was here near to cage. One of then loves to eat the food on my hand without fear, ahah, totally crazy! c:
