Grey

Grey (more frequent in British English) or gray (more frequent in American English) is an intermediate colour between black and white. It is a neutral or achromatic colour, meaning that it has no chroma. 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 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 modesty. Only one per cent of respondents chose it as their favorite colour. Provided by Wikipedia
