Many animals have superior night vision compared to humans, but this doesn’t necessarily mean better color vision. Most animals sacrifice color vision for better light sensitivity in low-light conditions. Key differences include:
- Tapetum lucidum: A reflective layer many animals have behind their retina that enhances night vision
- Rod cells: Animals like cats have more rod cells (for night vision) than cone cells (for color)
- Pupil shape: Vertical pupils in cats and other nocturnal animals allow better light control
While humans lose most color vision in darkness, some nocturnal animals like owls and cats can detect slight color variations in very low light. However, their color perception is generally less detailed than human daytime color vision.
