For the new study, published April 26 in the Journal of Physics: Photonics, the researchers used pump-probe microscopy to analyze samples of cadmium yellow paint subjected to an artificial aging process.

From Van Gogh’s sunflowers to Edvard Munch’s “The Scream,” there’s no shortage of seminal artwork that was made with a striking hue known as cadmium yellow.

Monet’s rich yellow sunsets and landscapes could only be painted after the invention of cadmium yellow in the early 19th century.
