CLEAN : Science unveils master painters' secrets

The video discusses a tool invented four decades ago for analyzing molecules in art, particularly effective for highly colored pigments. It introduces enhanced Raman scattering, a technique for identifying colors in microscopic samples. The video also explores how original colors in paintings can change over time, such as a vibrant yellow turning into a dull pinkish grey.
