Which color set represents the primary colors of light used on digital displays?

• A. Red, Green, and Blue
• B. Red, Green, and Yellow
• C. Cyan, Magenta, Yellow
• D. White, Black, Gray

Answer: (A)

Digital displays work with light in an additive color model. The primary colors of light are red, green, and blue. By varying the brightness of each channel, a screen can reproduce the full range of colors, and when all three are at full intensity, the result is white. The other color sets don’t serve as the light primaries: cyan, magenta, and yellow are used in subtractive color systems like printing; yellow is produced by mixing red and green light rather than being a primary itself; and white, black, and gray are neutral tones, not color primaries.
