In RGB mode, what are the primary colors used?

In RGB mode, the primary colors used are red, green, and blue. This color model is based on the additive color theory, where colors are created by combining these three hues in various intensities. When these three colors of light are combined at full intensity, they produce white light. The RGB color model is widely used in various digital contexts, including computer screens and televisions, where the blending of these colors creates a broad spectrum of colors viewed by the user.

The other choices include colors that do not belong to the RGB model or follow a different color mixing process. For example, the combination of magenta, cyan, and yellow are relevant in the CMY and CMYK color models used in printing, which is a subtractive color model. Thus, understanding the RGB model is crucial for anyone working in audio, video, and film technology, as it directly applies to the way colors are represented and displayed in digital media.
