Many Colors

How many colors of a cat and actually see how many are there?
It has been shown that cats can see colors. I found it interesting. I'll edit with the correct answer if nobody knows.
The cats senses – Vision. The cat's field of vision is wide, in exchange for his vision is a little blurred at the edge of the field. It looks good colors as human beings, in short, sees colors the same way that humans do color blind, for example, appears red and yellow colors like blue and green hues. In cats can see color return to the ultraviolet light is invisible to humans. The cat needs very little light to see, the starlight poor penetration into a night of clouds can be enough. This is partly due to its luminous eyes, the retina of the cat has a fluorescent layer (tapetum lucidum), which reflects light, so the cat in a can "use light more than once."
