The "New" Dilutions
Pearl --- Light Black ---
Other Dun --- Mushroom --- Hanoverian Cream
The NewDilutions list (no
longer in use; try searching for the color in which you're
interested on Facebook) and
to study and document color dilutions
could not (AT THAT TIME)
be explained by known equine color genetics.
took on another function : that of explaining and
tracking (initially) some of the
previously "unknown new dilutions"
which are now known to be
by a gene
which we named Pearl.

that particular horse, or a link, below, to see the section about
each color phenomenon.
This webmaster has been contacted through the
years by folks wanting to know about the "mushroom" color in ponies.
For many years, it was on our "back burner", especially
since it seemed, at first, to be simply explained by "silver".
Now it's known that red (ee) ponies show this dilution (which therefore
can't be "just silver"), plus there has been a new form of
red (e) discovered that is quite possibly the cause. At
this time, it seems to exist only in a very few pony families.
See the link to the farm on our "Mushroom"
page for more info.
The newest dilution gene discovered, "Pearl",
not only occurs in Andalusians, Lusitanos, Pasos, and American Paint horses, but has also been confirmed to exist in
the breed(s) known as Gypsy Horses. (See the Pearl section,
and then follow the links to the Gypsy Horse examples.)
Congratulations and kudos to the
members of the former firstname.lastname@example.org, Carolyn Shepard, Dr. Cecilia Penedo at UCDavis,
and all of you other equine color researchers
and horse owner/breeders
who worked to identify, name & rename this rare and amazing, elusive, recessive
and cream-activated gene (Pearl).
DNA Color Testing
If you wish to have complete documentation of your horse's
color (breeding) potential, you should have your horse DNA tested for as many
color genes as he/she could possibly have.
This group gains no profit from
any of these labs; the above is simply our opinion. If you wish to look
into testing your horse, you may consult the list of all labs of which we know and
the tests they are currently able to here, HERE.
(OR to be more current, just look on the UC Davis web site for their
tests. The only one I'm not sure they do is for "brown", a
variant of bay.
If you know of changes that should be made to
