Colorimetry is a method that applies color intensity to ascertain the chemical concentrations. It is founded on Beer-Lambert Law, whereby the absorbance at a given wavelength is proportional to the concentration. It is popular in environmental and biochemical testing.
A spectrophotometer and colorimeter are certain instruments used by scientists to measure color by quantifying reflected or transmitted light. The results are presented in color spaces, such as L*a*b*, RGB, or XYZ. This enables the accuracy of comparison and tracking of the changes in color in chemical or material research.
