gray

Grey (British English) or gray (American English) is an intermediate color between black and white. It is a neutral or achromatic color, meaning literally that it is a color "without color." This means that there are equal components of red, green, and blue. The variations in intensity of these colors uniformly produce different shades of grey. It is the color of a cloud-covered sky, of ash and of lead.
The first recorded use of grey as a color name in the English language was in AD 700. Grey is the dominant spelling in European and Commonwealth English, although gray remained in common usage in the UK until the second half of the 20th century. Gray has been the preferred American spelling since approximately 1825, although grey is an accepted variant.
In Europe and the United States, surveys show that grey is the color most commonly associated with neutrality, conformity, boredom, uncertainty, old age, indifference, and modesty. Only one percent of respondents chose it as their favorite color.
