colorimetry
Measuring light absorption
Colorimetry is the science of measuring and quantifying color.
It encompasses techniques for determining color values, comparing colors objectively, and establishing color standards.
The field has applications in printing, photography, food science, and quality control: The lab used colorimetry to ensure consistent paint batches.
In chemistry, colorimetry specifically refers to analyzing substances by measuring light absorption in colored solutions.
