    Default Brown vs. Bay?

    Why is Hoopy known as "brown" on her passport rather than "bay"? What is the difference between a brown and a bay horse, or are they actually the same thing? In my younger days of learning coat colours at "own a pony" days at the local RS, I was taught that horses weren't brown - they were bay, yet here I seem to have a brown pony

    She looks bay to me too, but definitely passported as brown (exmoors have to be inspected too before they get a passport, so they must have decided for some reason that she is brown not bay!) It's very confusing

    Well remembered!

    Brown ones have brown mane and tail, not black and don't have black points. Hoopy looks bay in the pic (and very cute!! )

    Molly's mane and tail are very dark brown but against black can see its not black and the tips of her ears are edged with darker brown, not black, No black on legs either.

    From a distance she looks almost black


    But close up you can see its brown

    Black points.. Basically.. Obviously colour genetics is far more in depth now do someone will come along that can explain further..

    The two basic colours are black and chestnut and are affected by several other gene types..


    Many horse colors are the result of dilution genes acting on the base colors. They all work similarly in that they dilute the main body color, but not always the color of the legs, mane, and tail. Bay is the most basic dilution color, and it is caused by the agouti gene diluting black. The black body hairs are diluted to a shade of brown while the legs, mane, and tail remain black. Like most dilution genes, agouti is dominant, so if a horse carries it, it will be expressed.

    Agouti is technically not a seperate gene, but rather a piece of the black gene called an allele. It can occur in three forms: A-agouti (meaning the horse is bay), a-non agouti (meaning the horse remains black), and At-brown (a color often confused with dark bay, but genetically different from bay).



    Brown is also a dilution that acts on black as I mentioned above. Though it looks similar to dark bay, it is genetically different. Brown (or seal brown) horses are characterized by having a black coat with brown hairs on their muzzles, flanks, inner forearms, and inner thighs. Seattle Slew is an excellent example of this color.

    Hmm that makes sense, thank you all So by that description she is definitely bay! I wonder if the exmoor pony society has a different description of brown, as most exmoor I've seen are similar in colouring to Hoop, and they're often described as "brown". Although this one:

    looks like she could be brown as she doesn't seem to have black points, is that right? I guess also horses change colour a lot since foals!

    Yeah.. I have photos of Jack at birth and now on his birthday thread..

    This was Iggy at 3 days



    And at 2 years.. He's on the right.. The black points develop a bit later, even in Clevies and pretty much all of them are bay.. There's the odd rare one with red points but it's frowned upon

    b_22 she looks bay to me

    Hoopy is a very cute bay!

    Phils is dark bay (IMO lol), he looks brown in summer, black in winter but his legs are always black.
