I agree with fowlwitch. I was not successful in my attempt at photos of my group's skin. It is a grayish color. So they will need work too. I'm no expert by any means, so here is a definition/explanation of what a land race is. Please note that this was copied from wikipedia.
A
landrace is a
domesticated, locally adapted,
[1][2][3] traditional variety
[4] of a species of animal or plant that has developed over time, through
adaptation to its natural and cultural
environment of
agriculture and
pastoralism, and due to isolation from other populations of the species.
[1] Landraces are generally distinguished from
cultivars, and from
breeds in the standardized sense, although the term
landrace breed is sometimes used as distinguished from the term
standardized breed when referring to cattle.
[5]
Specimens of a landrace tend to be relatively genetically uniform, but are more diverse than members of a standardized or formal breed.
[1]Some standardized animal breeds originate from attempts to make landraces more consistent through
selective breeding and a landrace may become a more formal breed with the creation of a
breed registry and/or publication of a
breed standard. In such a case, the landrace may be thought of as a "stage" in breed development. However, in other cases, formalizing a landrace may result in the genetic resource of a landrace being lost through
crossbreeding.
[1] Landraces are distinct from ancestral wild
species of modern stock, and from separate species or subspecies derived from the same ancestor as modern domestic stock. Landraces are not all derived from ancient stock largely unmodified by human breeding interests. In a number of cases, most commonly dogs and horses, domestic animals have escaped in sufficient numbers in an area to breed
feralpopulations that, through
evolutionary pressure, can form new landraces in only a few centuries. In other cases, simple failure to maintain breeding regimens can do the same.[
