Some People See More Colors Than Most
In Some People See More Colors Than Most, learn how tetrachromacy, a rare condition that allows some people to see more colors than most, is diagnosed. The video highlights how scientists test for this ability by challenging individuals like Concherta to identify colors that only tetrachromats can see. This video is excerpted from BBC’s The World’s Most Extraordinary People, a documentary series revealing how rare medical conditions inspire groundbreaking scientific discoveries.
Lesson Express
Q: What does it mean to be a tetrachromat?
A: A tetrachromat has four types of color-detecting cones in their eyes, allowing them to see a wider range of colors than most people.
Q: How do scientists test to see if someone is a tetrachromat?
A: Scientists have individuals choose the "odd" color from a set, selecting colors that only tetrachromats can perceive due to their additional cone.
Q: Why is it important to study tetrachromacy?
A: Studying tetrachromacy helps us understand how the brain processes color and how rare conditions like this can inform our knowledge of sensory perception and human abilities.
