I can't say I have a favorite color. I am not a fan of the brindle's at all and so-so on cafe-au-lait, but otherwise, no real favorites. I love black, white, brown, cream, apricot, red, silver, gray, blue, parti, and definitely Phantom (but then, I have had a doberman for in my home for 30 years now so I think I come by the love of that color naturally..lol).
My main thing is temperament, temperament, temperament; good, proper structure, expressive face/eyes, if the dog has these, then you can slap just about any color on it for me.
