RGB (Red, Green and Blue)

RGB (Red, Green and Blue); which by mixing can be used to produce all the colours in the visible spectrum. RGB brightness and contrast controls allow you to individually adjust colors for the darker and lighter portions of the screen. Regardless of the technology (LCD or CRT) the colors red, green, and blue are mixed in varying degrees to produce all the colors displayed. Red, green, and blue at full intensity create white.

It is the normal format of a computer monitor, and some examples of use are: RGB input or output goes directly to the entrance or exit from the computer.

This is used in reference to component signals produced to display color images by a traditional analog computer monitor and/or projector as a composite signal or dual H/V signals (Horizontal sync/Vertical sync). Very common signal for analog computer displays.

SRGB (Standard Red, Green, and Blue):

SRGB stands for Standard Red, Green, and Blue — the colors used as the basis of color reproduction in CRT monitors, LCD panels, projectors, printers and other devices. The sRGB color profile uses independent color coordinates which can be translated into the corresponding color coordinates on each device, ensuring natural-looking, uniform color reproduction, regardless of the color system used by the device itself.
