Platinum foxes, like white mark, can have heterochromia of the eyes or entirely blue eyes. Platinum is also an incompletely dominant gene that is lethal in homozygous condition. Thus, platinum foxes should not be bred to one another. This results in reduced litter sizes due to embryonic death. Fox kits that are sometimes born are all white with blue eyes. These kits are very weak and usually die immediately after birth and generally do not survive into adulthood. The same can be expected if platinum is bred to whitemark or Georgian white. If one wishes to produce a platinum fox, it is best to mate a platinum parent with a silver or other non-lethal color.
Platinum foxes carrying the pearl factor tend to have a paler coat color, similar to silver foxes carrying the pearl factor. The Platinum coloration can range from very pale to dark, and indiscernible from whitemark.
