grey

Grey or gray (American English alternative; see spelling differences) is an intermediate color between black and white. It is a neutral color or achromatic color, meaning literally that it is a color "without color", because it can be composed of black and white. 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, 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 North America, 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.

    Grey plastic pipe in heating system.

    Doing some decorating I discovered that some of the central heating pipe work is grey plastic. System installed 20 years ago by previous owners. My question is was that normal practice back then and is it likely to cause any problems in future? All exposed pipe work to rads is copper.
