  A parti Yorkie isn't supposed to be anything. It's a color fault. 
This is also from the YTCA website:  
Parti-Color Yorkshire Terriers?
 
Do not be fooled into buying one of these dogs.  
 
Now that Designer Dogs are the rage, the “new” Parti-Color Yorkie is certain to draw attention. While we have had problems in the past with “rare gold” Yorkshire Terriers being advertised, the parti-color is a new one! While some breeds have an occasional mismark and some breeds do have a gene for a white dog, we do not. Had there been a problem with white markings, piebald dogs, or white dogs, it would have been addressed in our Standard. Due to unscrupulous breeders advertising parti-colored Yorkshire Terriers at premium prices, our members voted unanimously at our annual meeting to add a disqualification for these and other off colored dogs. 
 
The Yorkshire Terrier is a tan dog with a blue saddle. The “rare gold” Yorkie is actually a dog that appears as such due to an improper saddle pattern. Show breeders have seen this and commonly call it running gold. When the dog is cut down, you can see that the blue saddle does not come down far enough. The Yorkshire Terrier blue saddle extends lower than some of the other black and tan terriers extending to the elbow and also to the hock on the rear leg. Gold hairs can occur in the blue and black or blue hairs can appear in the gold. These faults are addressed in the Yorkshire Terrier Standard. These dogs have serious faults and they too should not be sold as "rare" but placed in loving homes as they are very incorrect. Yorkies do not have white markings…never have. A small white strip is sometimes seen on the chest of newborns but this always turns to tan within a few weeks. The AKC registration form for Yorkshire Terriers allows for four choices: blue and tan, blue and gold, black and tan, black and gold. There is no provision for markings.
