Are horses scared of certain colours?

While there is some anecdotal evidence suggesting that certain horses may be fearful or reactive to specific colors, there is no scientific evidence to support the claim that horses are generally afraid of particular colors. Horses have dichromatic vision, meaning they can only perceive two primary colors: blue and yellow. Their perception of colors differs significantly from humans, who have trichromatic vision.

Horses' fear or anxiety often arises from various factors such as past experiences, training methods, and individual temperaments rather than specific colors. It is essential to approach each horse as an individual and understand its unique characteristics and experiences to determine the root of any fear or anxiety they may exhibit.
