The apple in your hand is not actually red
In short: Why do objects have color? Neil deGrasse Tyson explores the physics of light and human physiology to explain how our senses interpret the world around us.
Color is a product of both external physics and internal biology. The video examines why an object like a red apple appears red, specifically exploring what happens when it is illuminated by a light source that lacks red wavelengths. It also addresses the famous 'blue dress vs. gold dress' debate to illustrate how our brains process visual information.
The discussion covers the properties of white light and the concept of 'dark adaptation.' By understanding these mechanisms, we can better appreciate the relationship between scientific advancement and our physiological senses.
