The RGB (Red, Green, Blue) color model is an additive color system used to describe and reproduce color, particularly in electronic display technology. It is based on the principle that by mixing varying intensities of three primary colors—red, green, and blue—any other visible color can be accurately approximated. In this system, the colors are mixed by adding light wavelengths together, which means that mixing all three primaries at full intensity results in white light. The specific ratio of the three components determines the resultant hue, saturation, and brightness of the color, making it the fundamental standard for digital imaging, monitors, and other light-emitting displays.
