Which color model uses varying intensities of red, green, and blue light to reproduce colors?

• A. Hexadecimal Number System
• B. Image
• C. RGB
• D. file extensions

Answer: (C)

Colors on screens are produced using the RGB color model, which represents colors as varying intensities of red, green, and blue light. This additive color model is based on light: by adjusting how bright each of the three components is, you can create a wide range of colors; combining all three at full intensity yields white, while turning all off yields black. This is exactly how digital displays emit color, since they generate light rather than pigments. The idea of adjusting intensities is what lets you reproduce images and user interface colors on a monitor. The other options describe things that are not color models: the hexadecimal number system is a way to write numbers (often used to specify color values in web pages), an image is a picture file, and file extensions identify file types. So the color model that uses varying intensities of red, green, and blue light to reproduce colors is RGB.
