Red, green, and blue

Red, green, and blue

• A. CMYK
• B. RGB
• C. HSV
• D. LAB

Answer: (B)

This question tests which color model uses red, green, and blue as its basic light primaries. In the additive color model used by digital displays, colors are created by emitting light in red, green, and blue. Varying the intensities of these primaries mixes to form other colors, and combining all three at full strength yields white. That’s why screens, cameras, and many digital imaging systems rely on RGB. CMYK is subtractive and used in printing (cyan, magenta, yellow, black). HSV represents color by hue, saturation, and value rather than by primary light colors. LAB is a perceptual color space designed to be device-independent, not defined by a specific set of light primaries.
