What if you could create a color, one that no one had ever seen before? That’s what a team of UC Berkeley scientists set out to do, and in the process they found a new green — one so intense a camera could not capture it and a printer could not replicate it. How they did it and how their discovery may change what we know about color science and how the eye works are the subjects of a New Yorker article by Rivka Galchen, “What Would It Mean to See a New Color?” We talk to Austin Roorda and Ren Ng, the scientists behind the work, and Galchen.
Guests:
- Rivka Galchen, Contributor, The New Yorker Magazine – She wrote the article “What Would It Mean to See A New Color?”
- Ren Ng, professor, University of California Berkeley Electrical Engineering and Computer Sciences
- Austin Roorda, professor, Optometry and Vision Science University of Waterloo, runs the Roorda Lab at UC Berkeley
