Color Measurements of Standards for Grades of Cotton

Abstract

Measurements of the color of standards for grades of cotton, which were made in the United States Department of Agriculture, are shown in a series of diagrams. These illustrate the relation of the grades to each other in color, how the color may change during a period of years, and color measurements of the original standards, copies of them, and of the standards adopted in 1946 to become effective August 1, 1947.
