I always like something a little different. As far as dogs, I have had a Hairless Chinese Crested and now have 2 Japanese Chins.
When I had my Crested put down to old age related problems, I was going to get another Chin. Then I decided to get a Yorkie as I have wanted one for a long long time.
I was supposed to go see a traditional Yorkie and then called a lady that had Biewers. When we got there and I saw Zachary, I fell in love with him. It is personal taste. Even though people don't say "Oh, it's a Yorkie" but rather "He looks sort of like a Yorkie", Zachary is a healthy, happy and smart Biewer. Even though I love the look of a Biewer and would probably get another if I was to get another Yorkie, I would chose a healthy "traditional" Yorkie over a less than healthy Biewer.
I mean, really, what is the problem? If the dog is healthy, happy and smart like my Zachary

, your only decision should be the color YOU want.
Trying to "limit" the colors of a healthy dog makes no sense. You don't want a Chocolate? (I would get one if I could). Get another color. Let those that enjoy something "different" enjoy it.
