Colorimetry is the science of measuring and quantifying colors. It involves using instruments to determine the concentration of colored substances in a solution or the color properties of materials. This technique is essential in various fields, including chemistry, biology, and art, to ensure accurate color representation and analysis. The primary tool used in colorimetry is the colorimeter, which measures the intensity of light absorbed or transmitted by a sample. By comparing the results to standard color charts, scientists can identify and quantify specific colors, aiding in quality control, environmental monitoring, and product development.
