Which term describes color information independent of brightness in video?

Explanation:
Chrominance describes the color information separate from brightness. In video, color is often encoded as Y'CbCr, where Y' carries luminance (brightness) and Cb and Cr carry the color details—hue and saturation. This separation lets you adjust brightness without altering color and makes techniques like chroma subsampling possible for efficient video compression. The other options don’t fit: luminance is the brightness component, RGB Color Space is a full color model that combines channels and isn’t independent of brightness, and a teleprompter is unrelated to color information.
