The speaker begins by explaining that color is not a physical property, but a perception of our brain. Using a phone as a light source, they demonstrate how shifting the background light can transform white light into black. They argue that black is a shade of white, suggesting that black and white are different shades of the same thing.
The speaker then uses a mini projector to illustrate that what appears as black on a screen is actually less light compared to the surrounding white. They further explain that when you combine the primary colors of light - red, green, and blue - you get white light.
However, they also point out that when you mix red, green, and blue paint together, you get black paint. This is because paints absorb most of the light in the room, making them appear dark. The speaker concludes by noting that brown is just a darker shade of orange, or brown light.
Finally, they discuss the subjective nature of color, suggesting that we can never truly know that the color we see is the same as the one someone else sees, as color is subjective and perceived differently by each person.
