What does "RGB" stand for in the context of color?

In the context of color, "RGB" stands for Red, Green, Blue. This model is used in various applications including digital displays and image editing, as it is based on the way that light colors combine. Each of the three colors in the RGB model can vary in intensity, and when combined in different ways, they produce a broad spectrum of colors.

This model is particularly significant in digital media because screens emit light, and by adjusting the intensity of red, green, and blue light, we can create almost any color the human eye can perceive. For instance, mixing red and green light at full intensity creates yellow, while combining all three colors at full intensity results in white light. The fundamental basis of RGB is anchored in additive color theory, which is central to how we understand and work with color in digital formats.
