Grey (or gray) is the color of black and white mixed together.

Gray is the color of an elephant, cement, and pencil writing. Gray often looks like someone made black lighter, but not so light that it is white.

In the United Kingdom, Canada, Australia, South Africa, India, Ireland, and New Zealand, as well as a few other countries, this word is spelled "grey". In the United States, it is spelled "gray". The first recorded use of gray as a color name in English was in 700 A.D.
