Can cats only see in black and white?

Cat's eyes have mostly rods and some cones, so theoretically they can perceive some colors, but they don't need to. They function on brightness more than colour, which makes it easier for them to see in the dark. The cat's pupil can open 3 times wider than a human's, allowing much more light in.
Cats are not color blind, however. They see some colors, but not all colors.
Cats seem to be able to distinguish between higher frequency colors, meaning cats respond to the colors purple, blue, green and possibly yellow range. Red, orange and brown colors appear to fall outside cats color range and are most likely seen as shades of grey or purple.
Purple, blue and green appear to be the strongest colors perceived by cats. Tests suggest cats can distinguish between more shades or levels of gray than can humans.
