Many animals have superior night vision compared to humans, but their color perception at night varies. Here’s how it works:
- Most animals have more rod cells (responsible for night vision) than humans
- Cats and dogs have a reflective layer called the tapetum lucidum that enhances night vision
- Some nocturnal animals sacrifice color vision for better light sensitivity
While humans lose most color vision in low light conditions as we switch from cone to rod cell vision, some animals maintain limited color perception. For example, owls have highly specialized retinas that allow them to see some colors even in very dim light. However, this enhanced night vision often comes at the expense of color discrimination during daylight hours.
