Depends on the color of the mare before it turned gray.
When the mare was:
Chestnut/Sorrel/Red
25% Palomino
25% Gray out of Palomino
25% Gray out of Chestnut
25% Chestnut

It depends on whether the stallion or mare is homogeneous for a certain color gene. You could have many possibilities, but a logical predication would be either palomino, chestnut, white, or bay. (Bay and chestnut being the two most common horse colors.)
Like with humans you have to look at genetics. The dominant gene will trump the others usually.
There is no way to answer this question. A palomino is a color not a breed or type of horse. Many different breeds accept the palomino color in their registries, from miniature horses to Quarter Horses and everything in between.
Palomino is a color and not a true breed! the palomino color has been around since ancient times.
Palomino is not a breed. Palomino is a COLOR. Just like paint horses are not a breed, they are a COLOR. Palomino can be found in most but not all breeds of horses.
Since palomino is a color, a palomino can weigh as much as any other type of horse.
The Palomino registry is a color registry. The horse must be the correct color to be registered with the breed. A horse can be a palomino and not a member of the breed, but the breed has only palomino colored horses in it. Palomino is a breed and a color although it is most often used as the color for example i have a Palomino Dun Appaloosa
palomino is a horse color, not a breed.
No one really know how the Palomino colored horse got its name. Queen Ysabella of Spain sent one stallion and five brood mares to new Spain know called Mexico. She sent them to improve the new world. Some people think it came from that others think it came from Dick Halliday registering his palomino horse El Rey De Los Reyes. so no one really knows. Hope this helps!
Palomino is a color, not a breed. Palomino coloring can be found in many breeds, therefore the length of the horse will be determined more by the breed than the color.
This depends greatly on what color the stallion was before he greyed out. Grey is simply a modifying gene that causes the base color of a horse to loose pigment and become white with age, it's not an actual color itself. That said the foal would likely inherit one copy of the cream gene from the palomino dam, so would likely be some kind of dilute color and depending on the stallions grey status either heterozygous or homozygous he would have a 50% to 100% chance of going grey.
So a Palomino mare is probably genetically AaCrcree, aaCrcree or she could carry At The term brown for the stallion is ambiguous so he could be AtacrcrEe AtAcrcrEE or AtAtcrcrEE or AtAtcrcrEe or he could carry the rare B gene or actually be liver chestnut. For the sake of simplicity we will assume that brown means black with a tan or red muzzle and flanks. They could produce a palomino, chestnut, bay, brown, black, smokey black, buckskin 50% chance of a dilute (cream foal) what color the cream gene modifies if inherited is basically an unknown.
