RGB and CMYK are two important color models used in digital art. They each have different uses and are better for different situations.

RGB (Red, Green, Blue)
RGB is used mainly for screens like computers and phones. It creates colors by mixing different amounts of red, green, and blue light. For example, when all three colors are used at their brightest, you get white. If there's no light at all, it makes black. This model works well for digital displays since they give off light.

CMYK (Cyan, Magenta, Yellow, Black)
CMYK is different because it’s used for printing. Instead of adding light, it takes light away. Colors are made by subtracting amounts of cyan, magenta, yellow, and black from white paper. If you mix all four colors together, you should get black, but often it turns out to be a muddy brown. This model is better for printed material since it reflects light.

Why These Differences Matter
Knowing these differences is important for managing colors in digital art. When artists create something for screens using RGB and then want to print it with CMYK, they need to pay attention to how colors might change. A bright blue on a screen can look much duller when printed. This change can affect how the artwork is received.

In short, understanding RGB and CMYK helps artists make designs that look good whether they are on screens or printed. This way, their artistic ideas come to life in every format.
