The Minolta Colorimeter is a reflectance spectrophotometer that calculates color appearance parameters from the reflectance spectrum. The instrument reports color appearance in the *L,a*,b* color scale. L* is the luminosity function, indicating how dark/light the sample is on a scale of 0 to 100. The a* scale reports intensity of red (+a*) or green (-a) color components. The b scale reports the intensity of the yellow (+b*) or blue (-b*) color components.
Information Required by Submitter:
Any special handling requirements should be submitted with the samples.
This method and the Hunter Colorimeter method are similar and report using the same scales. However, the optics of the instruments differ, resulting in slightly different interpretations of the reflectance spectra. The result is that the two instruments will provide slightly different color values on the same sample. This may be important if data is compared to previous results generated by other laboratories.
Example of Reported Result:
(Values below indicate an orange color appearance)
L* = 58
a* = 22
b* = 32
