Colorful horses
 

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.

Mabey when you place your mouse over the horse a sign appears over the horse showing the male sign or the female sign. :)

THANK YOU EXCALIBUR...being the slow person i am (j.k of course:D ) i have know clue which horses are male and female same with pets and other animals that arent pets so that would be very good....sorta like maloria's thing where if you mouse over a character then there stats show up

Brown horses are male, the white ones female - for pets, yellow is female and red male.
My point is that different colors would improve the look of GK and add to RP. I think right-corner-info would do.
