The basic working principle of colorimetric sensing is colorimetry, which is a visible change in color that results from a chemical interaction between the sensing/detecting material and the target ...

Colorimetry is, as the name suggests, the study of color. The technique differs from spectroscopy, which measures spectral output across a range of wavelengths, as it is concerned with how color is ...

The science of measuring color and color appearance is vital: The perception of color is a subjective process where the brain responds to stimuli produced when incoming light reacts with the several ...
