What color model is referred to as the additive color process?

What element does an additive system of color use?

The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.

Why do we use cyan magenta and yellow?

To reproduce color, the CMYK color model codes for absorbing light rather than emitting it (as is assumed by RGB). The ‘K’ component absorbs all wavelengths and is therefore achromatic. The Cyan, Magenta, and Yellow components are used for color reproduction and they may be viewed as the inverse of RGB.

What happens if you print RGB?

In this case, the printer creates images by mixing CMYK colors to varying degrees with ink instead of digitally as it is with RGB. This is called subtractive mixing. If with RGB, all colors started as black, with CMYK, they begin as white, and each layer of ink decreases the brightness to create the desired color.
