Why are Greyhounds called Greyhounds?

do you know why Greyhounds are called Greyhounds?
I always wonder why they are called Greyhounds when there are so many of them which are not gray.

The origins of the name "greyhound" has many theories, but remains unclear. For many, the assumption is that refers to the dog's colour. However, there are relatively few greyhounds that are grey. It has also been theorized that it is a derivative of the the following words: Greek Hound; Great Hound; or Gaze Hound. In the end, the actual colour of a greyhound becomes secondary to its gentle grace, and combination of intelligence and sensitivity.
