Color has long been an important factor in the marketing of extracted honey. In recognition of the importance of this fact, the Department established a color classification for extracted honey in.1927 and made it a part of the United States Standards for Grades of Extracted Honey.

The official instrument for determining color classification according to these standards has been the Pfund wedge comparator, which has been desribed in previous publications and is commercially available.
