Abstract

This new instrument for measuring the color of cotton is based on a satisfactory application of the Hunter Color and Color-Difference Meter to problems of raw cotton measurement. It is designed to be fully automatic and self-standardizing, and graphically to show values for reflectance (Rd) and yellowness (+b) on a two-dimensional chart. It is self-contained in a movable cabinet, with a minimum of exposed parts. Although this particular model is limited to measurements in the range of cotton color, the principles on which it is designed are adaptable to other limited ranges of color, in either two or three dimensions, thus providing an automatic, self-standardizing small-difference calorimeter for other limited ranges of color.
