2. Colorimetric analysis - Wikipedia

   en.wikipedia.org/wiki/Colorimetric_analysis

   Colorimetric analysis is a method of determining the concentration of a chemical element or chemical compound in a solution with the aid of a color reagent.It is applicable to both organic compounds and inorganic compounds and may be used with or without an enzymatic stage.

3. Colorimeter (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Colorimeter_(chemistry)

   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.

4. Colorimetry - Wikipedia

   en.wikipedia.org/wiki/Colorimetry

   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.

5. Colorimetry (chemical method) - Wikipedia

   en.wikipedia.org/wiki/Colorimetry_(chemical_method)

   In physical and analytical chemistry, colorimetry or colourimetry is a technique used to determine the concentration of colored compounds in solution. [1] A colorimeter is a device used to test the magnitude of a solution by measuring its absorbance of a specific wavelength of light (not to be confused with the tristimulus colorimeter used to ...

6. CIE 1931 color space - Wikipedia

   en.wikipedia.org/wiki/CIE_1931_color_space

   The laws can be summarized in three principles: Additivity: if a third light (z) is added equally to two metamers (a & b), the results are metamers (i.e. if a = b then a + z = b + z). Proportionality: if the luminances of two metamers are equally increased or reduced by some constant (m), the results are metamers (i.e. if a = b then a*m = b*m).

7. Metamerism (color) - Wikipedia

   en.wikipedia.org/wiki/Metamerism_(color)

   In colorimetry, metamerism is a perceived matching of colors with different (nonmatching) spectral power distributions. Colors that match this way are called metamers . A spectral power distribution describes the proportion of total light given off (emitted, transmitted, or reflected) by a color sample at each visible wavelength; it defines the ...
