Which color mode is best for images viewed on screens?

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

Answer: (B)

Images viewed on screens rely on light emitted by the display, so color is produced by adding light through different channels. This additive approach uses red, green, and blue light, and by adjusting how bright each channel is, a screen can create the full range of colors you see. That makes RGB the natural color mode for digital images intended for screens, because it directly matches how displays generate color and how our eyes perceive colored light. Other options fit different contexts: grayscale carries only brightness, CMYK is subtractive and used for printing with inks, and LAB is a perceptual color space used for color management rather than direct display. In practice, RGB (often with sRGB as the standard) yields predictable, screen-accurate results.
