Pointed coloration: The points on the face, ears, legs, and tail are dense and distinct, and all are the same color. The facial points, like a mask, cover the entire face to the whisker pads and may extend to the ears, but this color should not extend to the top of the head. There should be no light-colored or white hairs on the pointed areas.
Faults: Inappropriate (different color from the standard below or spotted) color of the nose and paw pads, excessively soft and mushy body (translator's note: feeling like it's falling apart), and no obvious protruding cartilage that can be felt by normal touching.

Eyes other than blue. Toes and/or feet of a different color. Incorrect number of toes. Underjaw or overjaw due to malocclusion. Long hair.
