Eyes

Do rabbits see color?
Rabbits are not color-blind but their color perception is limited. The retinas of mammals contain two kinds of light-senstive cells -- cones and rods. Cones detect bright light and contain pigments that give the ability to see color while rods are activated under low light and lack the color-vision pigments.

The retinas of the domestic European rabbit have been studied to hold many more rods than cones -- rods in the domestic rabbit retina reach a peak density of about 300,000 per square millimeter in contrast with cones which reach a peak density of about 18,000 per square millimeter. These cones are sensitive to either green or blue light but not to red, so rabbits are limited to dichromatic (two-color) vision. Most of the retina is dominated by green-sensitive cones, but there is a small area with no green cones and many blue cones. It is unknown what this means for a rabbit's color vision, but rabbits do not seem to pay much attention to color.
