Are horses color blind?

Question

Are horses color blind?

Answer 1

well kinda they can only see a limited amount of colors!

Answer 2

Horses have limited color vision, which appears to be similar to one of the less common forms of color blindness in humans—they perceive red and blue, but they cannot distinguish between green and shades of gray.

Answer 3

No.  I was always told this. But, it seemed odd that everytime they painted the jumps at the stable I rode at the horses would spook even though they had been over those same jumps many times.  A horse's eyesight is about 20/33 or worse than the standard human vision of 20/20.  He can see almost 360 degrees around him with only a 3 degree blind spot at his tail.  The horse's depth and color perception is worse than humans but his night vision is much better.  Horse aren't color blind but do have less acute perception of color than humans.  See articles below.
