Colorimetry is "the science and technology used to quantify and describe physically the human color perception". [1] It is similar to spectrophotometry , but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.
A colorimeter is a device used to test the concentration of a solution by measuring its absorbance of a specific wavelength of light. To use this device, different solutions must be made, and a control (usually a mixture of distilled water and another solution) is first filled into a cuvette and placed inside a colorimeter to calibrate the machine.
A colorimeter is a device used in colorimetry that measures the absorbance of particular wavelengths of light by a specific solution. [1] [2] It is commonly used to determine the concentration of a known solute in a given solution by the application of the Beer–Lambert law, which states that the concentration of a solute is proportional to the absorbance.
The equipment required is a colorimeter, some cuvettes and a suitable color reagent. The process may be automated, e.g. by the use of an AutoAnalyzer or by flow injection analysis. Recently, colorimetric analyses developed for colorimeters have been adapted for use with plate readers to speed up analysis and reduce the waste stream. [1]
In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value , and chroma (color intensity). It was created by Albert H. Munsell in the first decade of the 20th century and adopted by the United States Department of Agriculture (USDA) as the official color system ...

These experiments sought to quantify the typical human chromatic response (color perception) and define it as the standard (colorimetric) observer. The standard observer is defined by the 3 color matching functions in one of the CIE 1931 color spaces.
Forensic colorimetry, or forensic color analysis, is the examination of specimen color for purposes of forensic investigation.Typical specimens involved in color analyses include pigments, dyes, or other objects that are distinguishable by their intrinsic color.
