Squirrel Colour Vision
Most squirrel species have cone-dominated retinas and have dichromatic color vision that is mediated by green and blue cones. One interesting study, however, showed squirrels being able to distinguish green and red biscuits (source). A squirrel's color perception relies on specialized photoreceptor cells within their retina: rods and cones.
Rod cells are responsible for low-light vision and detect changes in light intensity, contributing to monochrome vision, while cone cells are crucial for color detection and function optimally in brighter light. How Squirrels See A squirrel's eye contains specialized photoreceptor cells responsible for detecting light. These cells are primarily categorized into two types: rods and cones.

Rods are highly sensitive to light intensity, making them adept at detecting motion and aiding vision in dim conditions. Cones, on the other hand, are responsible for color perception and the detection of fine. Squirrels possess a type of vision known as dichromatic, meaning they are able to distinguish between two colors.
Red and green are the two colors which squirrels can see the clearest, while blue is the color which they can barely make out. Are Squirrels Color Blind? Squirrels have excellent dichromatic color vision, but it makes them limited when telling reds and greens apart. Dichromatic vision means that squirrels are able to tell the difference between red and green from different colors because of their ability to decipher them apart for the rest of the color wheel.

Squirrels can distinguish some different shades of blue and green colors.
But, they face difficulty in seeing long wavelength colors like red. Hence, they cannot identify any shades of red. Though the squirrels have limited color perception, the colors they can see are enough for their foraging and navigating of their area.

Are Squirrels Color Blind? Unveiling the Truth About Their Vision Paul West / Pet And Wildlife Care Have you ever pondered what the world looks like through the eyes of a squirrel? It's a question that tickles the curiosity of many nature enthusiasts and animal lovers. As you watch these agile creatures dash across your yard, you might be surprised to learn that their vision is quite. Squirrels are fascinating creatures, and their ability to see the world is quite different from ours.
You might wonder, squirrels can see some colors, but not red and green, as they have dichromatic vision. This means their eyes are equipped to detect primarily blue and yellow hues, which helps them navigate their environments and find food. In comparison, squirrels have two types of cones that are sensitive to a wider range of wavelengths, allowing them to detect colors that are invisible to humans, such as ultraviolet light.
While squirrels do have some level of color perception, their color vision is not as well.
