"Black bay"... What are the genetics? Offspring possibility?

I have a "black bay" Clydesdale mare who I am breeding to a flaxened chestnut stallion.
I am a bit frustrated that I can't find a breakdown of genotype for different types of color categories. There is a wide range of 'bay' color... from gorgeous blood red bay to a practically black bay (like my mare). For chestnuts, how does the 'flaxen' effect change things?
I'd like to daydream about foal possibilities, but I don't know how to factor in my mares specific dark coloring and the stallions flaxen.
Can anyone give me insights or send me to an easy-to-understand website?
Thanks!

Bay and black bay (aka brown) are thought to be seperate alleles of the Agouti Locus.
If your Clydesdale mare is black bay then she is probably ata This means that depending on the chestnut stallion she could produce Bay, Black bay, or black. If she is one of those rare Clydesdales that carry chestnut then that could be a possibility as well.
Flaxen is thought to only affect chestnut base coats so again unless your mare carries a chestnut allele is unlikely it will figure into the equation. The inheritance of flaxen is not well understood but is thought to be polygenic with perhaps several genes contributing degrees of lightness.
Hope that helps. If not feel free to ask more questions.
