Colorimeter
From Wikipedia, the free encyclopedia
A colorimeter (invented by Jan Szczepanik) is a device used to measure the absorbance of a specific solution. It allows the absorbance of a solution at a particular wavelength of light to be determined. The most common application of a colorimeter is to determine the concentration of a known solute. Different chemical substances absorb different wavelengths of light. The concentration of a solute is proportional to the absorbance.
The optics filter in the colorimeter is used to select the wavelength of light which the solute absorbs the most, in order to maximise accuracy.
Colorimeters usually measure results in percent transmission, percent absorption, or both.
In graphic design, colorimeters are used to generate color profiles for equipment in the workflow. Accurate color profiles are important to ensure that screen displays match the final printed products.

You mean cOlorimeters maybe ?
They are used to match colors of solution with colors of standard solution.
If a color is due to impurities, for example in a drug, a pharmacopoeia states the maximum color that the solution of that drug should have.
If the drug is colored, normally there is a range of color intensity in which you should stay, if you want to sell the drug.
Standard solutions have the colors coded with names: Y1 Y2 Y3 Y4 and so on are various intesities of yellow.
YG is for yellowgreen
G for green
R for red
and so on.
