Which term describes the color model that uses red, green, and blue as primaries?

• A. CMYK Color
• B. YUV
• C. LAB
• D. RGB Color

Answer: (D)

RGB Color is the term for the color model that uses red, green, and blue as primaries. It’s an additive color model used by digital screens, where colors are created by mixing light from these three channels. When red, green, and blue light are combined at full intensity, the result is white; with none of them lit, it’s black. This is why TVs, monitors, and phone screens render images by adjusting the intensities of red, green, and blue light.

The other options belong to different contexts: CMYK Color is used for printing and relies on subtractive mixing with cyan, magenta, yellow, and black; YUV is a video encoding scheme that separates brightness from color information and isn’t defined by a primaries-based light mix; LAB is a perceptual color space designed to approximate human vision and isn’t built from a simple trio of primary colors.
