How does the RGB color model differ from the CMYK model?

The RGB color model is fundamentally an additive color model, which means it creates colors by combining light in varying intensities of red, green, and blue. This model is predominantly used for digital screens, such as computer monitors, televisions, and smartphones, where colors are produced by mixing these three primary colors of light. When red, green, and blue light are combined at full intensity, they produce white light. Conversely, when none of the colors are present, the result is black.

In contrast, the CMYK model is a subtractive color model used primarily in color printing. It stands for Cyan, Magenta, Yellow, and Key (Black). In this model, colors are created by subtracting varying percentages of light absorbed by the colored inks. When these colors are mixed, they absorb light and thus produce a range of colors, resulting in a darker appearance. The presence of all four colors leads to black, but due to impurities in inks, pure black is often produced separately with the Key component.

The distinction between the two models is critical for creators and designers as it informs how they should prepare their artwork for different media. Therefore, the correct answer correctly identifies that RGB is an additive model for screens while CMYK is a subtractive model
