Color test meter |
| abstract |
ABSTRACT A colorimeter for converting a color output to an electrical signal comprises a color chart for comparing to a color which is to be converted, and means for generating an elec-trical signal which corresponds to a favorable comparison of the color to the color chart. The colors of the chart are located with respect to the means for generating an electrical signal so that the latter is conveniently located to be actuated when the color which is to be converted approximates a color on the chart. The means for generating an electrical signal comprises a plural-ity of switches, each having two states. Means responsive to the states of the switches provides the electrical signal which corresponds to a favorable comparison of the color to the color chart. Means are provided for coupling the electrical switches to the means for combining the states of the switches. |
