Cats are not color blind.
They see some colors, but not all colors. And they see colors differently than
humans do.Cats are able to detect color but do not see the intensity of color
that humans see. Blue, green, purple and yellow are all within the range of
sight for a cat. Red, orange and brown are seen as tones of gray. Cats' eyes
have both rods and cones. Unlike human eyes, however, cats' eyes have a high
percentage of rods, the portion of the eye that is used for night vision and
detecting motion. With a lower percentage of cones that are used for the
perception of color, cat vision is more equipped to see in low light and to
detect motion than it is to detect color.
