Colorful horses

[Satrek2000]

I know (or think) that black horses have already been suggested. I also know that there'd be a problem concerning the gender or how to tell it. I still think there could be different color schemes - by means of slight variations of the present, like different shades of brown, or patched horses, coming off the egg at random - always with the dar one being male and the while female. This way, it should be obvious what gender a horse is in most cases, but not all the time - plus it could be added to the right-corner-info, as it isn't really necessary to see a horse's gender at first glance - the owner should know, any anybody else shouldn't care. This way, even black horses should be possible, being really rare, as well as golden (or gold-brown) horses being rare females.
