And a "green" Serinus canaria domestica canary is pretty indistinguishable from a wild Serinus canaria.
Your severely confusing what I said.
Selective breeding is not domesticating over two generations to get a green canary that is only genetically different through a few generations, where it is physically identical.
Changing a wolf to a poodle is domestication, which takes hundreds of years and generations. But not just changing the physical appearance, but the way they act around humans. If an animal will come to the door to greet you with excitement for reasons other than food and water, I think that is important in domestication as well.
I have horses greet me, my cat and dog greet me, and I've seen small pigs greet their owners.

I don't think there are any 'domesticated hamsters', because most of them are identical to their wild ancestors. Generations with mice are a bit different because they breed at such an incredibly fast rate, they can be altered easier through selective breeding.
However, I don't think anyone can show me a 'mini mouse with curly hair' or a mouse that isn't the same as a field mouse with a different color.
Colors do not change the breed of animal, which is domestication in my book.
