  • Test piece coloration comparative decision unit
    Patent number: 5160979
    Abstract: An apparatus is provided for making color comparisons between a test sample and a plurality of color samples. The color samples are arranged on a circle on a rotatable member and are successively moved into position adjacent a test sample. When an operator determines that a color sample adjacent the test sample is closest in color to the test sample he operates a switch which causes a stored numerical value associated with that sample to be read out and displayed on a display device.
