There is No Pink Light

The video explains that pink is not a standalone color in the visible light spectrum. Instead, it is a combination of red and blue light, perceived by our brains as a single color. The absence of pink in the rainbow is due to the gap between red and violet, where invisible wavelengths like radio waves and gamma rays exist. Since these wavelengths are not visible, pink is used as a placeholder. In terms of light, pink can be considered as 'minus green,' as it is the result of removing green from white light.
