Digital displays use which color model to reproduce color?

• A. CMYK
• B. RGB
• C. HSV
• D. LAB

Answer: (B)

Digital displays reproduce color by emitting light from each pixel. This relies on the additive mixing of three primary light colors: red, green, and blue. By varying the intensity of each primary, screens can render a wide range of colors, and combining all three at full intensity produces white. That’s why this color model is the standard for digital displays. Other models have different roles: CMYK is subtractive and used in printing with inks; HSV describes color in terms of perception and is handy for choosing colors in software but isn’t how displays directly reproduce color; LAB is a perceptual, device‑independent space used in color science and color management, not the direct emission model of screens.
