If you're meaning on Howrse (the tags are confusing me a bit lol, sorry xD), the coat color would be at random. The color of the parents' coats do not affect the foal's, and it's at random.
Usually the darker color will dominate, the foals color will usually be the darker of the two. But sometimes it will depend on the genes too.
The following is a website that has a picture of a light bay horse. It is labeled and towards the bottom. All of these horses are Andalusians but the coat color is the same no matter the breed. http:/www.equiandalusian.com/plantilla.cfm?valor=SeccionCapas
there was none, they evolved from fox-like creatures
it would depend on what breed the horse/pony is, for example, a heavy horse breed will in most occasions be heavier than a pony but with a light weight horse breed there will be some pony breeds that are heavier. hope that helped :)
every light horse ( not draft horses)
The palomino is a breed and a color. The breed just has certain rules the horse must follow. like the parents must be palomino, and the horse must be a certain shade of gold, ect. The palomino as a color is just a golden color with a white mane and tail and dark skin, versus light pink skin, which would classify the horse as a champagne.
A chesnut is a light brown color horse and a palomino is a yellow or golden color horse, and a bay is a dark color horse.
it would appear black because no red light strikes it
it depeneds what breed it is
A buckskin is a color, not a breed of horse. A light horse's average lifespan is between 18-22 years old, tho some horses can live as old as 35. If it is a pony it can live even longer. If it is a draft horse it will be lucky to see 16-18 years old, tho the only true draft that comes in the buckskin color is a Fjord.
Standardbreds are used for harness racing.
A strawberry is red because it reflects red light. The sky is blue because it reflects blue light. Everything that looks a certain color absorbs every color but that one. The grass absorbs every color but green.
