The crossing between EE and ee always produces a black foal but that foal always carries the red gene. (Ee). If that horse is bred to a chestnut the foal will be chestnut half the time just like the heterozygous bay-chestnut crossing. If the bay is also heterozygous for agouti the foal has a 12.5% chance to be black. According to what geneticists taught 50 years ago, there would also be a 12.5% chance of liver chestnut. They believed that was what the genetic pattern aaee produced.
Gray foals are not always born black. They can also be bay or chestnut, depending on what its genetic base coat is, so that foal could appear chestnut or almost anything else depending on what color the gray stallion is underneath.
EA's genetics are not accurate at all. I bred a bay leopard appaloosa to a sooty palomino mare. They both had multiple layers of colors and markings in CAS. The foal got the base palomino plus his dam's sooty markings PLUS his sire's bay markings. Very weird looking.
I've been studying horse coat genetics for a long time and would be happy to share what I've learned. They seem to come up with something new all the time so there is always more to learn.

This was just a roguh example to help those who are basic with genetics, but if you would love to create a full thread in the equine book feel free to do so, We would love for others knowledge on horse genetics! for IRL purposes, also I know how you feel on EA's gnen pool mess ups. This was made by sapphire, just so people get a better understanding on the basics.
