Which three of the following colors are used to create pixels in most output devices?

• A. Red, Green, Blue
• B. Magenta, Yellow, Cyan
• C. Orange, Purple, Teal
• D. Red, Black, White

Answer: (A)

Pixels on most screens are created using an additive color model that blends red, green, and blue light. Each pixel is built from tiny red, green, and blue subpixels; by adjusting their intensities, the display can produce the full spectrum of colors. When all three are at full intensity, the pixel appears white; with none, it appears black. The other color sets aren’t used for this purpose: magenta, yellow, and cyan are the subtractive primaries used in printing; orange, purple, teal aren’t standard color primaries for displays; red, black, and white don’t form the primary color channels used to generate image colors on most screens.
