What Colors Can Deer Not See?: 1 Minute to Better Understand Deer Vision

Deer vision has evolved to help them survive in their natural environments, but it’s notably different from human sight. Deer are essentially red-green colorblind. They lack the red-sensitive cones present in humans, which means they see the world with a limited color spectrum. Most research suggests that deer cannot see colors at the longer end of the spectrum, such as red, orange, and likely certain shades of green, the way humans do. To deer, these colors generally appear as shades of gray or brown. On the other hand, they can easily detect blue and ultraviolet light, making shades in those ranges much more vivid and alerting to them. This is why hunters often wear orange vests for safety—other hunters can spot them, but deer cannot distinguish the bright orange from the green-brown forest (it simply blends in).

As a designer, understanding how different species perceive color goes beyond just visual impact; it affects function and safety. For example, choosing the right color tones for wildlife observation blinds, or even themed interior spaces with animal-inspired palettes, could benefit from the knowledge that some colors blend seamlessly into the surroundings, offering subtlety and concealment. When creating immersive spaces, considering perception—whether for animals or humans—can lead to more impactful and thoughtful interior design solutions.

Tips 1:

If you’re designing a space for nature observation or incorporating animal motifs, consider using earth tones that work harmoniously with both human and animal perception, creating an environment that feels authentic and calming.

FAQ

Q: What colors do deer see best?

A: Deer see blue and ultraviolet hues most vividly, as their eyes are sensitive to short wavelengths.

Q: Can deer see orange clothing?

A: To deer, orange appears as gray or brown, which is why hunters often wear blaze orange for visibility to humans but invisibility to deer.

Q: Are deer completely colorblind?

A: Deer are not completely colorblind, but they do not distinguish reds and greens, seeing mainly in shades of blue and yellow.

Q: Does camouflage work against deer vision?

A: Yes, camouflage using earth tones works well, as deer cannot distinguish some colors and focus more on movement and contrast than color.

Q: Why is understanding animal vision important in design?

A: Factoring in how animals perceive color ensures your space or structure is effective for its purpose, whether that’s for blending in or for creating themed environments that resonate with both human and animal visitors.
