White Wool
Most modern domesticated sheep grow white wool. This is because white wool is more desirable in the
commercial market because it can be dyed any color. However, sheep with white wool may have
different color faces and legs.

On the other hand, hand spinners, weavers, and other wool craftsmen often prefer to work with "natural colored" wool. Wool is produced in many beautiful colors: black, gray, silver, moorit, brown, and red.

It's All In the Genes
It is not uncommon for black or colored lambs to appear in a white flock. However, in order for this to happen, both of the lamb's parents must be carrying a gene for color.
Fleece Inheritance
The inheritance of fleece or coat color in sheep is quite complicated. Different genes control what
color the fleece will be, what pattern it will be, and whether the fleece will be spotted.

Changing Colors
The lambs of some breeds are born black and their fleeces will change to white or gray as they get
older.

Spotted Fleeces
One of the most uniquely colored breeds is the Jacob. The Jacob's fleece is described as white with black spots. The white wool grows out of white skin, while the black wool grows out of black skin. The Jacob's spotted fleece is referenced in the Bible. Prior to the 20th century, Jacob sheep were referred to as "piebald" sheep.

In the "Old West" a few colored sheep roamed the ranges. These animals were used as "markers", one for every 100 range sheep. The old timers counted the sheep and said, "once your markers are in, your flock is in".
