Which system is used to show colors from a video display?

The additive color system is utilized to display colors in video outputs by combining different intensities of the primary colors: red, green, and blue (RGB). When light from these three colors is added together in varying degrees, they can produce a wide spectrum of colors. This method works because it relies on the way humans perceive light. For instance, combining all three primary colors at their full intensity results in white light, while the absence of these colors results in black.

This system is employed in various electronic displays, such as computer monitors and televisions, where pixels emit light to create the images we see. The other options do not pertain to the video display context in this way. Subtractive color systems are typically used in color printing and rely on the absorption of light, while the terms "plus/minus color system" and "recover color system" do not represent established methods of color display in video technology. Understanding the additive color system is essential for anyone working with visual media, as it forms the foundation for how colors are rendered on screens.
