Most likely black, however, if they are not homozygous for black, the foal has a small chance of being chestnut.
If the stallion and mare are both aaEE all foals will be black.
If one parent is aaEe and the other is aaEE all foals will be black.
If both parents are aaEe there is a 75% chance that the foal will be black and a 25%
chance of a chestnut foal.

The foal could be a number of colors. Based on the description the stallion is either aaEe or aaEE. The mare is --ee (as her genetics at the agouti site is unknown). Research on the color of her parents and grandparents may be an indicator of the alleles at the agouti site. If the stallion is aaEe there is a 50% chance that the foal will be chestnut/sorrel. If the stallion is aaEE there will be no possibility of chestnut, however the resulting foal will be determined by the alleles that the mare has at the agouti site...which are currently unknown. If she has a single black parent, there is a 50% chance that the foal will be black (if the stallion is aaEE and a 25% chance of a black foal if the stallion is aaEe. Since black true black at the agouti site is homozygous recessive...it will be the mare's genetics at the agouti site that will determine the color of any non-chestnut foal.
If either horse is homozygous for roan the foal will be roan, if both are heterozygous there is a 75% chance that the foal will be roan. If by strawberry roan you mean the stallion is a bay roan as opposed to a chestnut roan, we can surmise that the stallion is Rn-A-E- The mare is Rn-aaE- The base color of the foal, without regard to whether it is roan is as follows If the stallion or mare is EE at the extension site they will produce either a bay or black foal...since the stallion is bay he could be AA (only bay foals) or Aa which will produce 50-50 bay or black with this mare. If both the mare and the stallion are Ee at the extension site there is a 25% chance of a chestnut foal.
Buckskin or Smoky Black
A dark brown horse. Possibly black. Possibly something with patches of the other color. According to a nifty foal color calulator that you can find a link to in the related links, the foal has a 70% chance of being bay, 24% chance of being black and a 7% chance of being chestnut.
In most cases, the father of a foal does not play a role in raising or caring for the foal. The responsibility of caring for and raising the foal falls mainly on the mother (mare). The stallion typically continues with his normal activities within the herd or separately.
foal
If the stallion carries the a gene and is heterozygous for roan your chances of a true blue roan are 50% if your mare is Ee. If she is EE there is no chance of a chestnut coated foal so the color of the foal will be controlled by the genetics of the stallion at the agouti site...either brown, bay or black.
Foal
If the black and white mare is aaEe and bred to a cremello stallion --eeCrCr the foal produced will be smokey black, buckskin, palomino based on the stallion's genetics at the Agouti site. If the mare is aaEE the foal will be smokey black, buckskin...no palomino foals. The type(s) of pattern genetics the mare carries will determine the spotting pattern of the foal (or lack there of).
Palomino Stallion --eeCrcr (the two -- are the unknown alleles at the Agouti site) Black Mare aaEe or aaEE (we will assume that the mare is not a smokey black which is a black horse carrying the creme gene). If either of the mare's parents is a chestnut her genetic makeup is aaEe which will simplify the choices. If either of the stallion's parents was a bay/buckskin (or both parents were bay based ) he will have the possibility of carrying the A allele. If the mare is aaEE no palomino or chestnut foal can be produced. If the stallion is aaeeCrcr 50% chance the foal will be black and 50% chance it will be smokey black. If the stallion is AaeeCrcr then there is a 25% chance the foal will be bay, 25% black, 25% smokey black, 25% buckskin. If the stallion is AAeeCrcr 50% buckskin and 50% bay If the mare is aaEe and the stallion is aaeeCr- the chances are 25% chestnut, 25% palomino, 25% black and 25% smokey black If the mare is aaEe and the stallion is AaeeCrcr the chances are 25% chestnut 25% palomino, 12.5% black, 12.5% bay, 12.5% smokey black, 12.5% buckskin. If the mare is aaEe and the stallion is AAee Crcr 25% palomino, 25% chestnut, 25% buckskin, 25% bay. Lots of possibilities here, always with a 50% chance of the foal with the Creme dilution. Unfortunatley, if the stallion carries a black allele or two black alleles your Creme dilutes will have a high probability of being smokey black which is often hard to tell from black.
Maiden mare: never been bred Open mare: had a foal but not bred back to a stallion Barren mare: bred or bred back to a stallion but not in foal
