The primary purpose of the RGB color model is for the display of images in electronic systems, such as on television screens and computer monitors and it's also used in digital photography. In order to create a color with RGB, three colored light beams one red, one green, and one blue must be superimposed. With no intensity, each of the three colors is perceived as black, while full intensity leads to a perception of seeing white.

Differing intensities produce the hue of a color, while the difference between the most and least intense of the colors makes the resulting color more or less saturated. The CMYK color model four-color process is a subtractive color model. CMYK works by partially or completely masking colors on a white background.

The printed ink reduces the light that would otherwise be reflected. When to use CMYK?

As technology progresses, programmers and engineers are able to find new ways to achieve color correction on computer and television displays through research, new tools, and advanced coding. While this opens many opportunities for technological advancements, the RGB color system still poses issues for printing and packaging!

Essentially, any colors produced with RGB on the digital space will not create the same output on the physical print. This is based on the color gamut, which in other words means that translating RGB to CMYK usually allows the color to convert only as close to the original appearance of the display screen. Therefore, working in a CMYK color space allows the artwork to look exactly or as close as possible to the real life design you will get when it becomes printing on paper or packaging.

The good news is your artwork designs can very easily be converted to the CMYK color model through whatever design program you may be using. However, the drawback for converting RGB color model designs to CMYK is that colors may need to be corrected again to produce something more close to your original design you created using RGB. As mentioned previously the most common use for the RGB color model is to display digital designs and images.

This includes things like your TV and computer monitor.
