I once owned a Bay Roan section B, his colour was amazing, he had a bay head, pink body, black mane and tail and legs.

I know breeding is a gamble, but if you bred a grey to a bay or vise versa could you get this colour?

Also when you clipped him his coat went steel grey, is it true they have two coats? lol

Any information aprieciated :P Thanks

With some roans you would only have a 50 50 chance of getting roan as it was beleived that you could only have 1 copy in a horse, but in some American Quarter Horse lines some individuals have been proven to be homozygous (2 roan genes) for the roan gene.

That being the case you then have to breed a bay! So if you breed a bay that carries no chestnut and has 2 bay genes to a red black or bay roan Homozygous QH then you will get a bay roan, other than that you will need to beat the odds.

Don't know that they have 2 coats but a scar on a roan will turn back to the base coat colour and not white.
 
my yearling can not decide between bay or bay roan!!!!!!! he was out of an appy QH x mare / colured (Tobanio) - I expected something a bit different so I was quite shocked with a bay foal with no white!!!
 
Anya You have yourself an appaloosa!!! If he is gradually getting more white in his coat then he probably has a copy of appaloosa varnish and will probably colour out with time, does he have stripy hooves, mottled skin in his private regions and or white sclera around his eyes??
 
The blue roan in my sig is out of a bay dad and a strawberry roan pbqh mare, 1 full brother is a strawberry roan, 1 bay and the other is the black/dark brown in my sig, so not sure how that works.
 
SO Bay dad was "A" (bay) carrying "a" (no bay = Black), "E" (black) and carrying "e " (Chestnut).

Mum was "ee" (no black ) and was for her A series "?a" (so unknown and black) Plus 1 roan

So basically between them they can produce any base colour + roan, which mum has put into the mix 2 out of 3 times.
 
Yep, red/strawberry roan to chestnut will give another chestnut so you have your "red" and providing you don't use a QH with 2 copies it's 50 50 on the roan.

Though there are some strange things going on with roans on the New Forest, there are quite a few that have patches across the back of roan but are not full roans!!! And sometimes ticking can mimic roan patches as well. When I get my laptop back from the menders I'll post some piccs!!
 
Karynk - no my boy has dark hooves black skin!!! his bay colouring is getting lighter with more intense white hairs on his head otherwise he is just speckled around his flanks and shoulder but that is it.......this will be 3rd time he has grown whire hairs then they disapear - the mare was a bay snowflake as a yearling then she lost her spots and is now almost a strawberry roan with maybe 5 white intense spots left.
 
Mottled skin on these is often very well hidden, it can even be in the mouth, with stripy teeth! It sounds like the mare has just inherited the varnish and that is affecting the whole coat and obliterating the spots, it is very rare but can happen. They can have no leopard at all they just fade slowly out and don't show any spots.

I had trouble getting one on the main register in the States last year she had one pink blob between her teats, had to creep up and take a picture, but now she is fading through her coat and has a bit more pink blobs developing.

This is how you get the Appaloosa crop outs I think, because the mottling on their skin is limited to underneath the coat and out of sight places and they are called non charateristic, but really they are very very minimal, sometimes they show no coat pattern but pass it on with the right mate.

Do you have any pictures?
