Which term describes any additive color space based on the RGB color model defined by three chromaticities of the red, green, and blue additive primaries?

• A. Chrominance
• B. Luminance
• C. RGB Color Space
• D. Interactive Video

Answer: (C)

An additive color space is defined by using three primaries of light—red, green, and blue. The exact color of each primary is described by chromaticity coordinates, and the space formed by combining those primaries is what we call an RGB color space. This term specifically identifies a color space based on the RGB model and its three chromaticities, which determine the gamut you can reproduce. Chrominance and luminance refer to color information separate from brightness, and interactive video isn’t a color-space term, so they don’t fit.
