Your mare is a bay roan her sire is a blue roan and blue roans go back 3 generations on the top side If you breed her to a blue roan will you get a blue roan?

Past colours in her family will have no say in her own offspring's colour. My buckskin mare has had her buckskin granddam and sire be bred to cremellos and produce palomino foals, so I thought she would too but instead I got a perlino, and the other three times I bred her to differant cremello stallions and yet again I got 2 perlinos and a buckskin.
(Here the buckskin mare's sire and dam must be Ee at the extention site. Based on the results gotten by breedings of their daughter, there is a very high probability that she is EE at the extension site hence no production of palomino.)
So no, you will not get a blue roan unless you specifically breed her to a heterozygous blue roan with a silver gene and make sure your mare is homozygous bay roan who has the silver gene as well but also has her black gene dominant over her red gene. f you know this info then you can assume your foal will be blue roan.
But there is a 2% chance she will produce a throwback (a foal the same as a past grandsire/granddam/great-grandsire & dam) that may very well be blue roan. This can happen even if you bred her to a colour that would only produce, say, a chestnut. My buckskin's mother is a palomino and she was supposed to be bay according to genetics. But she was a throwback. In technical terms, the percentage of getting a blue roan from a bay roan mare and blue stallion is 17.58%, with the probability of bay roan being 52.73%
Different take on this discussion:
This mare is AaE-Rn- (unknown allele at the extension site and unknown allele at the Rn site). We know the second allele at the Agouti site is a because her sire was aaE-Rn-
If the mare is bred to a blue roan stallion aaE-Rn- (again we don't know the
disposition of the alleles for this stallion at the extension or roan sites).
However, if either the mare or stallion is EE at the extension site there will be no chestnut or red roan foals produced from this mating.
In this instance where either the stallion or the mare is EE at the extension site,
there is a 50% chance that the foal will be black (aaE- or aaEE) and and 50% chance that the foal will be bay (AaEe or AaEE) in both cases there will be a
75% chance that the foal will be roan.
37.5% chance of blue roan (aaE-Rn-)
37.5% chance of bay roan (AaE-Rn-)
12.5% chance of bay (AaE-rnrn)
12.5% chance of black (aaE-rnrn)
If both the mare and stallion are Ee at the extension site the percentages will change to include chestnut and red roan foal possibilities.
If the stallion is homozygous for roan all foals produced from this mating will
be roan with and 50% of the foals will be homozygous for roan.
There is no information on the presence of the Silver or Taffy gene being represented in this breeding and it is not required to produce blue roan.

What color horse does not exist - the blue one or the rainbow?
the rainbow, there are blue roans.
How many roans are there?
Although not considered a rare coloration, roans are not nearly as common as chestnuts and bays. Roans, which come in several different hues, are about 1 in every 100 horses. The different varieties of roans are blue, black, red or strawberry. Much like the different types of grays such as rose, flea bitten, ect.
Are horses blue?
No, no horse breed is known to have blue hair anywhere on its body. However, there is a horse color known as a Blue Roan in which a black colored horse roans to a bluish color. The hairs themselves are not blue, they are actually black, but when mixed with a large number of white hairs, the human eye sees the color from a distance as blue.
What two horses create a blue roan?
It's not necessarily which two 'horses' create a blue roan color as Blue roan is just that a color and not a breed, therefore any two horses with the correct genetics can create a foal with blue roan coloring. Roan is a modifying gene that affects a horses base color. A blue roans base color is black. Both parents should be black and one should at least carry the roan gene. If a horse is Heterozygous for roan (Rr) then it has a 50/50 chance of passing along the roan gene. If one of the parents was Homozygous for roan (RR) then it will pass it along 100% of the time. Homozygous roans are hard to find though. However you can increase your odds of getting a blue roan foal by breeding two blue roans together. There used to be an old theory that said breeding two homozygous roans together would cause the fetus to die in -utero, however this has been disproved. Remember color breeding is not an exact science and you can get any number of colors based on the parents genetics. Also breeding strictly for color is typically detrimental to a breed as color can sometimes become favored over correct conformation.
When you breed a black and blue together what colors can you expect?
