Which of the following best describes the colors produced by mixing additive primary colors?

Mixing additive primary colors, which are red, green, and blue, results in a broad spectrum of colors due to the way light interacts with the human eye. In additive color mixing, when these primary colors are combined in various intensities or proportions, they create a range of secondary colors. For instance, red and green light together produce yellow, green and blue create cyan, and blue and red result in magenta. When all three primary colors are mixed at full intensity, they produce white light. This ability to create a diverse array of colors is what defines the additive color process, distinguishing it from subtractive color mixing, where colors are produced by removing wavelengths of light. Thus, the best description of colors produced by mixing additive primary colors is indeed a range of colors.
