Question

A dog can see only four colours. What are they?

Answer 1

Dogs are typically considered to have dichromatic vision, meaning they have the ability to see a limited range of colors compared to humans. While humans have trichromatic vision and can perceive a broad spectrum of colors, dogs primarily see shades of blue, yellow, and gray. The fourth color that dogs can perceive is still a subject of debate among scientists. Some research suggests that dogs may have limited sensitivity to green or a greenish-yellow color, while others argue that dogs' color vision is primarily limited to the blue and yellow spectrum. It is important to note that the exact range and perception of colors in dogs may vary among individuals and breeds.

Answer 2

A dog can see four colors: blue, yellow, gray, and shades of green. Dogs are not able to see the full range of colors that humans can, but they can still distinguish between different colors and shades.

Answer 3

The four colours a dog can see are blue, yellow, green and gray. This is because they have fewer cones, specialized cells in the retina, than humans. Dogs cannot see red or orange because their eyes lack the cones necessary to process these colours.
