Uncle Sam's color expert. Washington, D.C., Sept. 20. Miss Dorothy Nickerson is one person who can't afford to go color-blind. She is the color analyst of the U.S. Department of Agriculture and measures color as a means of grading and standardizing many agricultural products such as cotton, hay, fruits, vegetables, rice, honey, meat, grains, breads and many others. Miss Nickerson is using the special instrument designed by the Department of Agriculture for the measurement of color, in respect to hue, brilliance and chroma, the three elements distinguishing color. Miss Nickerson is measuring the color of cotton in this picture. 9/20/37
