**Summary:**

Scientists and art historians have definitively identified the striking blue pigment in Jackson Pollock’s famous painting, “Number 1A, 1948,” as manganese blue. By combining advanced spectroscopic techniques and computer modeling, researchers confirmed the pigment’s presence and explained how its unique molecular structure filters out green and violet light, allowing only blue light to pass through. This discovery has implications for art conservation, art history, and even materials science, suggesting the possibility of designing new pigments and optical materials by manipulating the electronic structure of inorganic compounds. The research highlights the intersection of art and science.

**Pollock’s Secret Blue: Scientists Uncover the Chemistry Behind a Masterpiece**

**New York, September 16, 2025** – For decades, the source of the vibrant blue coursing through Jackson Pollock’s “Number 1A, 1948” has remained a mystery. Now, a collaborative team of scientists and art historians from the U.S., including the Museum of Modern Art in New York, has definitively identified the elusive pigment as manganese blue, a once-popular but now-banned compound known for its pure hue and chemical stability.

Published today in the *Proceedings of the National Academy of Sciences*, the research details how advanced spectroscopic techniques, including resonance Raman spectroscopy and magnetic circular dichroism spectroscopy, were used in conjunction with computer modeling to analyze the pigment at a molecular level.

“This wasn’t just about satisfying curiosity,” explains lead researcher [Hypothetical Researcher Name]. “Knowing exactly which pigments Pollock used is crucial for authenticating his work and for guiding future conservation efforts.”

The team discovered that the blue color arises from charge-transfer bands, where electrons move from oxygen atoms to the manganese atom. This exchange filters out green and violet light, allowing the vibrant blue to shine through. This understanding, researchers say, could have broader implications.

“By adjusting the arrangement of other atoms around a metal atom, you can alter its electrons’ energy levels, thus changing the properties of the pigment,” explains [Hypothetical Researcher Name]. “This opens the door to designing entirely new pigments or optical materials with tailored properties, possibly even for use in advanced technologies like lasers.”

The findings are significant for conservators planning restoration work and give scholars more evidence of Pollock’s materials and choices. It could also open the possibility of identifying the same pigment in other works by Pollock and his contemporaries, like Willem de Kooning, who was also said to favour it.

The study also serves as a powerful reminder that art and science are not mutually exclusive fields. “A question born in front of a canvas – ‘what blue is this?’ – led to deeper insights into how matter and light interact,” the researchers wrote, underscoring the collaborative potential of art and science.
