According to Apple Inc., the RGB signal is the standard signal for most computer graphics and video files. It is named for the colors red, green and blue. These colors, in certain combinations and intensities, can create any other color. RGB also supports grayscale, ranging from black to white.
When the values of all components are 255, the result is pure white; when the values are 0, pure black. RGB images use three colors, or channels, to reproduce colors on screen. In 8âbits-per-channel images, the three channels translate to 24 (8 bits x 3 channels) bits of color information per pixel.
