Which color model uses additive blending?

Which color model uses additive blending?

• A. RGB
• B. CMYK
• C. LAB
• D. HSL

Answer: (A)

Additive blending refers to creating colors by adding light. On screens, every pixel emits light in red, green, and blue channels. When you mix these light primaries, you’re adding brightness: red plus green gives yellow, red plus blue gives magenta, green plus blue gives cyan, and all three at full intensity produce white. That light-based mixing is exactly how the RGB model works, which is why it’s the additive color model. CMYK uses pigments that subtract light to produce colors, not add light. LAB is a perceptual color space designed to reflect how humans see color rather than how light is mixed. HSL describes colors in terms of hue, saturation, and lightness and is derived from RGB, but the direct process it represents isn’t about additive light mixing.
