What is the main difference between RGB and CMYK color modes?

The main difference between RGB and CMYK color modes lies in their methods of color creation, which fundamentally relates to how color is produced in different contexts. RGB, which stands for Red, Green, Blue, is an additive color model. This means that colors are created by combining light. When you mix all three colors of light at their full intensity, the result is white light. This model is primarily used in devices that emit light, such as computer screens, televisions, and mobile devices, where varying the intensity of red, green, and blue light produces a wide spectrum of colors.

On the other hand, CMYK, which stands for Cyan, Magenta, Yellow, and Key (Black), operates on a subtractive color model. In this model, colors are created by subtracting varying percentages of light absorbed by the inks used in printing. When you mix all colors of ink at full saturation, you get a muddy brown color, and the presence of black ink helps to deepen colors and improve detail. CMYK is predominantly used in printing processes, where different combinations of inks are used to produce the desired colors on physical media.

This distinction in how colors are formed makes it critical for graphic designers to choose the right color mode based on the final
