Which of the following colors is NOT commonly associated with beer?

The color blue is not commonly associated with beer due to the nature of beer's typical color range, which includes hues like gold, brown, and amber. These colors result from the types of malts and the brewing process, which can range from pale golden beers such as lagers and pilsners to darker ales and stouts that showcase brown and amber shades. Blue, however, is not a color that arises naturally in the brewing process or in the ingredients typically used in beer production. Therefore, it stands apart as an anomaly when compared to the usual spectrum of beer colors.
