there are lots of pictures of Jane's dove boy Charliee on the forum and here are links to my mink boys/girls.
In the early days it is quite hard to tell the difference as young minks look very like doves. As they age though, a more 'orangey' colour replaces the grey/blue.

They are quite hard to tell apart, but as your hamster ages, the differences become more obvious.
Either way they are two of my favourite colours, lovely and soft pastel. So I am sure you have a very pretty hamster!
