Most likely you would get a light horse with either blue eyes or black eyes. It would matter though because, to be specific, there is no such thing as a white horse. Any horse that is grey or anything lighter than grey, unless cremello, is called grey, even if it has white mane/tail and a complete white body. To tell the difference between cremello and grey would be they eyes, with cremello being blue and and grey being black. Also, nostrils, genitals and any other place where there is no hair and skin shows, will be pink on cremello. On grey, those hairless places can be black or mottled. But to answer your question, it would either be cremello or white/grey, nowhere in between.
The basic colors are black, chestnut, bay, brown. The modifications would be; palomino, buckskin, smokey black, cremello, perlino, dun, champagne, appaloosas, paints, roans, etc...
A number of breeds of horses have the Creme gene which produces buckskin, palomino and smokey black in the Crcr (heterozygous) state and Perlino, Cremello and Smokey Creme in the CrCr (homozygous) state. Thoroughbreds, Quarter Horses, Morgans, Welsh Ponies, miniature horses, POAs, Appaloosas, Lusitanos and many of the warmblood breeds have the dilution genes to produce buckskins.
Buckskin or Smoky Black
Smokey was an American black bear.
Paint horses come in many colors and patterns. Colors can be:Bay, Black, Chestnut, brown. (The basic colors with one copy of cream are:Buckskin, Smokey black, Palomino, and smokey brown (also called brownskin), The basic colors with two copies of cream are: Perlino, Smokey Cream, Cremello, and either again Smokey brown or Moreno.) The above colors can have the following modifiers: Cream, Champagne, Silver, Grey, Roan, Rabicano, Dun. Pinto patterns are: Tobiano, Tovero, Frame, Sabino, Splash. It should be noted that Paint horses can also be solid in color as color is not a requirement.
Draft horses come in palomino, grey, cremello, black, and appaloosa.
All foals will be either chestnut, cremello or palomino. None of the foals from this mating could be bay, black, buckskin, perlino because both parents are homozygous ee at the extension site.
A smokey grulla is a black horse with a dun gene, and a cream gene.

The most likely colors are cremello, perlino, and smokey cream. Cremellos are chestnut horses with two cream genes. Cremello horses usually have almost-white hair, pale pink skin, and blue eyes. Perlinos are bay horses with two cream genes, and look very similar to cremellos, but often have a little bit of pigment in their manes and tails, and a tiny bit in their coat. Smokey creams are black horses with two cream genes. They tend to be a tiny bit darker, with a little bit of pigment in the mane and tail, but still have pink skin and blue eyes.
