The examination and analysis of colors and light spectra using specialized optical instruments and techniques.
From Greek 'chroma' (color) + 'skopeia' (examination), similar to words like endoscopy and spectroscopy that describe the practice of examining something with instruments.
Chromatoscopy became a powerful diagnostic tool in both art and science—museums use it to authenticate paintings and detect hidden layers, while scientists use it to identify chemical composition by color signatures.
