When luminance and chroma are combined together they create the complete definition, YUV or HSV, of the color information which can be converted into RGB.

What does the term chrominance mean?
chrominance in American English
(ˈkroumənəns) noun. Optics. the difference in color quality between a color and a reference color that has an equal brightness and a specified chromaticity.
What recording formats combine the luminance and chroma information?
Composite video is also referred to as CVBS, which stands for color, video, blanking, and sync, or composite video baseband signal. It combines the brightness information (luma), the color information (chroma), and the synchronizing signals on just one cable. The connector is typically an RCA jack.
What is the significant of separating luminance and chrominance in color processing?
There is at least one extremely good reason to process luminance and chrominance separately: Detail is in the luminance, noise exists everywhere. When working with color images, many processing algorithms and procedures can perform separation of pixel values into their luminance and chrominance components.
What is chrominance in image processing?
Chrominance (chroma or C for short) is the signal used in video systems to convey the color information of the picture (see YUV color model), separately from the accompanying luma signal (or Y' for short).
What is included in chrominance signal?
In the NTSC system, the chrominance signal is an alternating current of precisely specified frequency (3.579545 ± 0.000010 megahertz), the precision permitting its accurate recovery at the receiver even in the presence of severe noise or interference.
