Grey or gray is an intermediate color between black and white. It is a neutral or achromatic color, meaning that it has no chroma. It is formed when the RGB values are equal, but not 0 or 255. It is the color of a rain or storm cloud, of ash, and of lead. The first recorded use of grey as a color name in the English language was in 700 CE. Grey is the dominant spelling in European and Commonwealth English, while gray is more common in American English; however, both spellings are valid in both varieties of English. In Europe and North America, surveys show that grey is the color most commonly associated with neutrality, conformity, boredom, uncertainty, old age, indifference, and humility. Only one percent of respondents chose it as their favorite color.
