How do CMYK and RGB render differently?

Both CMYK and RGB color scales render colors differently due to the process of mixing colors and how much mixing is needed. Colors need to be converted correctly in order to meet the correct color profile, depending on the medium. Since RGB has a larger scale of available colors, this scale may work better to produce specific colors that are vibrant, depending on the product. In print mediums, RGB colors will not be as vibrant as they appear on-screen. CMYK colors are more accurate on screen and in print because it has a more limited range of possible colors. Both color modes must be properly converted using various design softwares in order to produce true colors. Colors viewed both on screen and in print mediums will vary.
