Abstract

This Uganda Standard provides numbers that correlate with visual ratings of yellowness or whiteness of white and near-white or colorless object-color specimens, viewed in daylight by an observer with normal color vision. White textiles, paints, and plastics are a few of the materials that can be described by the indices of yellowness or whiteness calculated by this practice. (This standard is an adoption of ASTM E313-15, Standard Practice for Calculating Yellowness and Whiteness Indices from Instrumentally Measured Color Coordinates). This standard was published on 15 June 2021.
