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.
RGB stands for red, green, and blue. This program visually combines three raster map layers to form a color image. For each layer, the corresponding component from the layer's color table is used (e.g. for the red layer, the red component is used, and so on).
