From the breed standard site I posted:

Eyes almond shaped, moderately spaced and set a trifle obliquely. Eyes may be brown or blue in color; one of each or parti-colored are acceptable. Faults--Eyes set too obliquely; set too close together.

And.......

Color
All colors from black to pure white are allowed. A variety of markings on the head is common, including many striking patterns not found in other breeds.
