Well from what I have seen/read is:
All colors will "fade" to some degree.
No matter the color you are looking for if you want it to stay as dark as possible look for a dog will little to no blue or silver in the background.
One way to tell if the pup will be silver is that they will have white in between the pads of their feet.
I have noticed that Cafe Au Lait and Silver Beige can be interchangeable terms for a fading brown.
Its almost impossible to tell what color the puppy will be just buy looking at under 8 weeks of age, it gets better at around 12 to 14 weeks.
