It really does take a lot of work to win a color class. Your clipping and grooming skills have to be impeccable, not to mention the time you will spend in the prep area making sure that your horse is as shiny and pristine as it possibly can be. Unfortunately, there is no standard to what wins or does well in a color class. If the judges happen to like greys, that's what they will place, if it's a judge who favors buckskins, they will pin a buckskin first. A few even like solid blacks. What's important to remember, is that whatever happens, don't be upset with the results, there is absolutely nothing you can do, to enhance your chances of winning this class, besides pretty grooming. You can not practice, or train your horse to be the color that judge likes that day, especially when you have no control over what the judge will like. Good Luck!
