What Is Color?

Explore the fascinating world of color in this illuminating World Science Festival video hosted by Alan Alda. Delve into the complexities of human vision, examining how our eyes process a small portion of the electromagnetic spectrum to create the vibrant hues we perceive. Discover how other animals interpret these same wavelengths differently and even perceive colors beyond human capabilities. Learn about synesthesia, a unique neurological condition that allows some individuals to experience colors associated with music, words, or other stimuli. Join vision researcher Jay Neitz and neuroscientists David Eagleman, Kaitlyn Hova, and Bevil Conway as they guide you through the intricacies of color perception, brain function, and the construction of reality. Witness a special performance by violinist and synesthete Kaitlyn Hova, demonstrating the unique way her brain processes music and color.
