Understanding Colors and Light

The video explains that the colors of the rainbow correspond to different wavelengths of visible light, but pink is not among them. Pink is a mix of red and blue light, perceived by our brains as a single color. When creating a color wheel, there's a gap between red and blue, filled by pink, representing invisible light wavelengths like radio waves and x-rays. Pink can also be described as 'minus-green,' as it is what's left when green is removed from white light.
