Which process involves mixing the three primary colors of light: red, blue, and green?

The process that involves mixing the three primary colors of light—red, blue, and green—is referred to as color addition. This method relies on the additive color model, where different colors of light combine to create new colors. When red, blue, and green light are mixed in various combinations and intensities, they can produce a wide spectrum of colors, including white light when all three are mixed at full intensity.

In the context of light, color addition is a fundamental principle used in various devices such as computer screens and televisions, where tiny pixels emit these three colors to display images. The more light you add, the closer you get to white, demonstrating the characteristic of additive mixing.

While other terms such as color mixing, color combination, and color blending may relate to the general concept of combining colors, they do not specifically describe the process of mixing light in the same scientifically precise manner as color addition does. These other terms are more often associated with pigment and paint mixing, which involve subtractive color mixing, where colors combine by absorbing wavelengths of light, resulting in a different outcome compared to light mixing.
