A computer monitor generates three colors of light which are?

• A. CMY
• B. HSL
• C. RGB
• D. YCbCr

Answer: (C)

Color on screens comes from additive color mixing. A computer monitor emits light in three primaries: red, green, and blue. By varying how bright each of these colors is, the display can blend them to produce the full range of colors you see. When all three are at full intensity, you get white. So the set of primaries for light emission in displays is RGB. Other options refer to different concepts. CMY are subtractive primaries used with pigments in printing, not the light a monitor emits. HSL describes a way to represent colors in software by hue, saturation, and lightness, not the light produced by a display. YCbCr is a digital video color encoding method that separates luminance from chrominance for compression, not the monitor’s three light primaries.
