When did colours become so complicated??

Agouti is the gene that, simply stated, makes a genetically black horse brown/bay coloured by chasing the black pigment colouring to the extremities (ears, legs, mane and tail).
You cannot 'see' Agouti only view it's working on a genetically black horse.
A chestnut can carry agouti but will not express it. Cross this chestnut agouti-carrying horse with a genetically black horse, and if it passes on this agouti gene and the black passes on a black allele ... you get a brown/bay coloured foal.

Wouldn't know but I've got a pink mule :D (On his consignment note it says "Gelding,Chestnut roan also could be grey roan colour ??"...guess they didn't believe it either:D ,He's my Pink Punk Picasso)
 
I have often wondered - what colour is this mare?

She has a dorsal stripe in the bit of colour she has on her rump to her tail. Also note the roan patch on her neck.

They've always been this complicated, we breeders just kept it a secret :p
We have all our stallions color gene tested, but over the years I've gotten pretty good at working out the difference between, for example seal bay, sooty buckskin and smokey brown all of which can present almost identically
 
His base colour is bay.
His primary pattern is tobiano.
He also carries one of the forms of Leopard (appaloosa) ... I'm hazarding a guess at Varnish Roan.
He also carries probably Sabino.

If one of his parent's is a grey then discount the Varnish Roan and think instead greying Leopard blanket.

Either: A bay tobiano with Varnish Roan
Or: A greying bay tobiano with Leopard blanket.

Where his coat is grey/white, his skin is pink, would that still class him as being a bay?
