I'm going to get LAUNCHED on, but.
I think for the most part, nowadays, judges don't really judge color.
It's just that the colored horses aren't always as good.
If there's a class of 30 horses and 7 colored horses and NONE of them were that good, the judge shouldn't and won't place him. But now he 'doesn't like color'. You also have to realize that in a sea of bay, you stand out. Which means EVERY mistake you make will be seen and accounted for.
I think the color thing is old and done with for the most part. It's just that the top trainers aren't picking colored horses, so MOST of the best-trained horses... are still bays. lol
