Definining Blue, Lavander, Lilac And Cream In Sebastopols.

[pete55]

Hi Henk

Thanks for your input. Yes I had read that the Spotting gene may be autosomal. I'm hoping for more information from Sebastopol breeders whose results may demonstrate this. It would be useful to hear of more test matings

I can only say what I know from chickens but want to clarify what I know about the color blue. Blue (in chickens) is a black modifier, not a black diluter. One blue gene (yes, it is a gene) changes black to blue and gives a bird that looks blue. 2 genes for blue change black to splash. Blue is not self blue.

In chickens, lavender is a black diluter and is recessive, meaning the bird needs to get the gene from both parents. If the bird gets only 1 gene for lavender, the bird 'looks' black but carries lavender. In chickens, self blue and lavender are different names for the same color.

As for geese, I'll leave that up to you all. I've got Embdens and white Chinese, so I don't have to worry about colors

I would say that chicken blue ís a black diluter. Chocolate however is a degraded form of eumelanin, modified so to speak from black to brown.

So- if I am getting this correctly- sebbie color is very similar to muscovies? Lilac in sebbies is the same as Dun in chickens?

I have several colors, and want to introduce more colors next year and would really like a go-to reference like Henk's calcualtor, but for geese.

Dun in chickens is one gene. Platinum (dun+blue) or mauve (sexlinked chocolate + blue) is a better comparison.

Yes- like that! I have several colors to put in though and am not sure of the abbreviations. Buff, Buff saddleback, lavender, white, grey....

Also- what is the name for the color of female Cotton Patch geese? Its not grey, but not quite blue?

Thanks Henk!

I posted on here not long ago about how my "lavender" American geese from Holderreads aren't turning out the same color as our previous Lavender. I think, based on this discussion, they are Lilacs. Has that ever been seen in Americans? Would the Sebbie Forum be able to help identify the color?

If you can post good photo of your Seb, Pete 55 might be able to ID it
here or on the Seb Forum (link below).
I have lavenders and lilacs pics on my website.

Well, they aren't Sebes, but please Pete help!

I'm not sure what "kinds" of photos help ID them best. But here are some of what we have.


We "think" we have two lilacs or two creams or possibly one of each. We have a "known" lavender (Myrtle) and two "known" blues (Fred & Frank). I use the term known loosely as no one has been out here to ID them for me, but as far as I can tell from breeding/photos they are in fact what they are labeled.

One of our suspected lilacs is Beula, she has angel wing on her left side. The other one is S2 - not named yet, so we go by number.

Here is Beula in the middle, Frank on the left and Myrtle on the right

Here is Beula, in the shade:

Beula on left, Myrtle in back, S2 front center, Frank far right

Old photo of Myrtle molting

S2 in front, Myrtle in back

S2 close, Beula farthest away

Okay I will stop now, lol. I know that's a lot, but I'm trying everywhere to determine what their colors are. We know that Beula and S2 are a different color from Myrtle, but we just don't know what each color is. Any help is appreciated. Thanks!

Hi there

Im afraid its very tricky to say about definite colour just from the pictures and really any suspicions need to be confirmed by knowing the parentage and/or test matings. Buff is a very tricky colour to guage as there are variations in depth of colour and this also changes with the season. I have 2 female Buff dewlaps and one is darker than the other but they are both sisters. Their colour also changes with the time of the year and exposure to the sun. One sister is in a more shaded pen and is a darker Buff. It appears the sun does have a bleaching effect on the feathers.

However it does look like you have Blues in Frank and Fred. They appear to have a single Blue gene (heterozygous for Blue) whereas Myrtle appears to be a lighter blue colour and sometimes referred to as Lavander. This probably due to a pair of Blue genes (homozygous for Blue). Its not that straightforward as I can see some Buff colour in the wings in the photo of Myrtle when she is moulting. If she has a Buff gene then technically I would call her a Cream.

Beula and S2 do not appear to have any blue in their colour but only variations in depth of colour of Buff and from the pictures I would say they're both Buffs.

Sorry to confuse the picture further but maybe you could give more information on any test mating you have done and what you bought them as.
