Are large mouth bass fish color blind?

Yes, largemouth bass are partially color blind. They have four types of cone cells in their eyes, which allows them to see colors in the blue, green, and red spectrums. However, they are unable to see the color red, and they perceive greens and blues as different shades of yellow. This means that their color vision is similar to that of humans with red-cone color blindness, also known as protanopia.
