    • PURPOSE:To make it possible to cope with all hues by obtaining an allowance limit value based on the displayed color value of a target color which is to become an object, and determined the acceptability as to whether the displayed color value of a material under evaluation is located within the allowance limit value or not. CONSTITUTION:The spectroscopic reflectivity and the spectroscopic transmittance of a target color and a dyed sample are measured in a color measuring device 1. An allowance limit value is stored in a memory device 2. At this time, the allowance limit value is introduced based on the data which has been obtained from the result of the determination of the success or failure of the dyed sample with respect to the target color by several persons for determining the acceptabiity having the experiences for long years. In an operating device 3, whether the dyed sample is located within the allowance limit value or not is compared and operated, and the acceptability is determined. On a display device 4, the result of the color measurement of the dyed sample, the result of the determination of the acceptability and the like are displayed.
