Which color mode uses red, green, and blue and is used to display images on screens?

• A. CMYK color mode
• B. RGB color mode
• C. LAB color mode
• D. Grayscale

Answer: (B)

Colors on screens are created using additive color mixing with red, green, and blue light. A display emits light, and each pixel has red, green, and blue subpixels. By varying the intensity of these three channels, you combine light to produce a full range of colors, and when all three are at full intensity you get white. This is why the RGB color mode is used for images intended to be viewed on electronic screens. In contrast, CMYK is a subtractive model used for printing with inks, where colors are created by absorbing light. Grayscale uses only shades of gray and no color channels, so it doesn’t represent color. LAB is a perceptual color space used for color management and editing, not the standard display model for screen output.
