In the Jacob world sheep are either black and white or lilac (and white). Lilac refers to a color that is Not Black. That is usually gray maybe with a brown cast. This blog post shows photos of several lilac sheep. Many time people think Jacob sheep have brown spots, but that is because tips of the dark wool become unbleached. The wool is still dark at the skin. When you describe the Jacob sheep’s color you look at the facial markings. If the hair is black or gray(ish) that dictates the label for the color.
Griffin is a ram that was born in February 2024. Last fall when this photo was taken I wasn’t sure of his color but now I am. In this photo he looks black and white. Remember, it’s based on the facial markings. It may be hard to tell from just a photo as well.
This photo was taken shortly after shearing in January. The eye ring that is often part of the lilac coloring is obvious and the fleece looks gray.
In this photo it is much easier to tell the difference in color between Griffin on the left and Sterling on the right.

The lilac trait is recessive so breeding two lilacs should produce lilac lambs. When there is a black and white parent the appearance of lilac lambs means that there is lilac somewhere in the ancestry of the black parent. In Griffin’s case, both parents are black and white. There is a lilac great-great-granddam on his sire’s side and a great-grandsire and on his dam’s side.
Sometimes we wonder if all “not black” Jacob sheep have the same lilac genetics. This is being investigated now.
I took this photo a few days ago when Griffin was stuck on the fence. He must have had his front feet on the tray of the feeder and caught his horn over the top pipe along the fence. I couldn’t get him off and had to get Dan to help.
That is her pawing and looking restless during morning chores.
When she looked more as though she were in active labor I brought her into the barn. That was about 10:15.
At about noon the sac was visible.
This view, taken about 2:00 shows how, as labor progresses, the sides are sunken in front of the hips. I had been waiting for Sheena to have her lambs before I went to town, but I finally decided to make a quick trip. When I came back at 3:00 she was lying down and pushing but I saw only the nose, which at that point looked somewhat swollen. When I felt for the lamb position, the feet were at about a 2:00 position instead of below the head and out in front. I pushed the lamb back so that I could make sure that the feet matched up to the right lamb, brought them around to the 6:00 position and then pulled the lamb easily.
As soon as the lamb was out Sheena went to work.
The sac for the next lamb showed within a few minutes. 
Lamb #1 was on his feet within 8 minutes.
You can see this ram lamb’s horn buds.
Sheena barely noticed as she pushed out the second lamb about 15 minutes later.
Lamb #1 is mostly white.
Lamb #2 has a lot of color and has lilac markings. Catalyst is the sire.
This is the first lamb two days later.
Here is the second lamb.
Lamb #1. These aren’t usually a pretty side when just born. Slime, dirt, blood. 
Jacob ewes are usually very good mothers and the lambs are vigorous. Shelby was cleaning up her baby…
…even while pawing the ground and having contractions for the second.
I got them inside the barn and the lamb got to its feet and started looking for milk.
Lamb #2.
The first lamb is nursing while Shelby cleans the second.
I love the look of this one. These are both lilac ewe lambs sired by Catalyst.
Here they are three days later.
These lambs are listed on my
