How to tell dark bay from dark brown

So a brown can have a black mane and tail and black legs as long as they are lighter in the muzzle and stifle?

Is it possible for a bay horse to be light in those areas?

If it is light in those areas and is "bay" that means it is actually a brown.

Alright, I was just wondering. Learn something new everyday!

So is it that a certain type of gene is bay when another is brown?

Yep. And bay is dominant over brown. A horse can be both Bay (A) and Brown (At) as far as I know. The one that will show will be the bay. Confusing right?

Wait, now I'm confused, haha. Would my horse be brown instead of bay? Her papers say brown, but in Germany they say brown for everything from cherry bay to seal.

Actually, that makes quite a bit of sense (we just finished learning about how genetics work in science).

^ I think your horse would be bay because of the dark points. Especially if you look at the specific spots (Muzzle, elbows, etc)

Hmm...this means my "bay" is brown as well...

She is registered Bay on her papers though.

This horse is obviously "seal brown." A good horse coat chart can be found here.

would you mind asking a mod, or I can ask, if you start a thread. But would you explain colors and genetics to us who don't know a single thing about it?

Sure Alex. I would be willing to put something together. Think we could get members to "donate" pictures to the thread for examples? (to only be used on the thread of course!)
