CMYK vs RGB

RGB and CMYK are both good but for different uses. RGB is an additive, projected light colour system where as CMYK is a subtractive, reflective light colour system. This means that RGB maxes at white, which is the same as if you were to have all the lights on at full brightness. Whereas with CMYK you need to add different coloured inks to the original white paper to absorb or subtract the light that is reflected.

RGB refers to a system for representing the colours to be used on a computer display. Using a combination of blue, red and green to create a colour spectrum to obtain almost any colour imaginable. RGB is generally left with a much brighter and much cleaner result, which is why; it is used on computer display.

On the other hand CMYK refers to four inks used in colour printing; cyan, magenta, yellow and black. CMYK colours tend usually to be duller in comparison to the RGB colours. This is due to the combinations being made by CMYK being relatively dark.

What you must bare in mind when comparing and contrasting these two is that you cannot display the exact same colours in RGB and CMYK.
