sRGB and Adobe RGB are the color standards used by laptops to ensure that there are minimal color differences between the actual design color and the one that comes out in the print. NTSC or the National Television Standards Committee is more of a standardized unit as most of them come with 72 percent NTSC color gamut which is equivalent to 99 percent sRGB. In most cases, the NTSC color gamut is comparable to the Adobe color gamut.
