Wow! Look at them legs!! Solid black-- still an awesome color! ;) ..or bay.. still awesome.. solid horses with no white are very flashy to me.


What color was the stud?

Nope she's brown. :) See how even in the summer she is still really light along the butt and stifle area? That's some of the classic indicators of brown. So are the heavy lighter to darker seasonal changes. that means her foals are brown as well from the EEaa stud. :lol: Love it!

ETA Brown (At) is a variation of agouti as well as bay (A) is a variation of agouti.

K so i have apparently learned this wrong all these years? i thought the deciding factor of bay vs brown was black points. she has black mane and tail, black legs and black rimmed ears??

I have a brown one here who i would call for sure brown. no black points at all on body except for mane and tail

A registered color doesn't mean they are that color genetically. My mom registered a foal as a black and the filly genetically is brown, after a few years of pestering my mom, she had the papers changed to being registered as a black bay.

The agouti gene modifies the black, and there are three types of agouti and each has distinguishing features. It can be hard to tell which agouti is present on the foal unless you know the agouti the parents have. Browns are great at disguising as a bay, the tell tale proof is in their winter coat when they get light coloration on their soft spots.

Here is a colt born last spring:

He was registered as bay (agouti came from his heterogyzous grey chestnut based dam). Then he grew his winter coat, and all his soft spots were very light while the rest of him was very dark.


So, another case of a genetically brown horse being registered as bay. Hope that helps explain that registration is unreliable for color :D

:lol: It can be confusing and the registries are notorious for registering incorrect colors. :lol: Brown horses can and do have black manes, tails and legs, the reason is is that brown, just like bay, is a form of agouti which is what restricts black to certain areas. They just do so in different ways. There are actually three agouti genes bay (A), brown (At) and wild bay (A+). Tests from UCDavis and Animal genetics, when testing for agouti, are only testing for the lack of agouti (a), so their tests look like this aa (two non agouti), a_ (one non agouti) and _ _ (no non agouti genes found). PetDNA in Arizona actually tests for the brown gene (At).

They are different from bays in that they get a softer orangey/tan color around the eyes, muzzle, butt, sitfle area and behind the elbows. They can also vary in shade just like bays can.

PetDNA out of Arizona. UC Davis can test for agouti, but they can only tell you if there's a gene present, not which mutation it is. PetDNA found At and owns the test for it.

I'd guess this new colt is brown too. The dark patches on his face, withers, and along his back usually indicate a brown foal.
