Digital photographs displayed on screens use which color channels?

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

Answer: (C)

Digital screens reproduce color with Red, Green, and Blue channels. Each pixel is built from tiny red, green, and blue subpixels, and by adjusting how bright each one shines, the screen adds light to create the full spectrum of colors. This additive color model is why screens can produce white when all three channels are at full intensity, and black when none are on. The other color sets belong to different contexts: cyan, magenta, and yellow are used in subtractive printing processes, while black, white, and gray describe grayscale rather than color. So the standard trio for screen displays is Red, Green, and Blue.
