What colors are used on a monitor?

Monitors primarily use the RGB color model, which stands for Red, Green, and Blue. These three colors are combined in various intensities to create a wide spectrum of colors that we see on the screen. Each pixel on the monitor consists of subpixels for these three colors, which blend together to produce the final color perceived by the viewer. Additionally, some monitors may use variations like CMYK for printing purposes, but RGB remains the standard for display technology.
