Thank you both !
Yes they all are amazing but Belle is my favorite too - also Diablo because i don't know what he really is... from the day i get him, i don't know if he is hypo or ultra - he was sold as a amel, but when you look at Belle, Diablo could not be amel at all !
A pairing this year with Peanut (who is het. hypo) will tell us more information. The breeder of Diablo tell us, that he comes from a het. butter scaleless pairing, so he is also het. for amel and caramel.
I'm really excited about this year and I hope everything works like I tought.
Mrs. Grey is also the only one who is yellow arround her neck/mouth.We will see if her son Tinley will get yellow too, but i think thats an anery thing

But, i agree with your theory, Dragonling, yellow is shown only in her scales which you can see perfectly on the pichture i match
second is Diablo as a baby who looks a little bit like Sophi, but now he's totally different. Diablo always looks more 'white' arround the borders - Sophi have a dark colour arround her borders
