When you choose color profiles, colors are matched between devices as closely as possible by the color management module (CMM) of the Kodak Color Management System, which is the default CMM. Color management modules are also known as “color matching modules.” Note that the Microsoft ICM, Windows Color System, and Adobe CMM do not change the color profiles that are used by Corel PHOTO-PAINT. If you want the application to use the same color profiles as those of the selected color management module, you must select the appropriate color profiles in the Color Management dialog box. Color gamut is the range of colors that devices such as monitors or printers can reproduce. Colors that cannot be reproduced by the output device are called out-of-gamut colors. Such colors need to be replaced by colors from the color gamut of the output device. To determine how out-of-gamut colors are replaced, you can choose one of the following rendering intents: By enabling the gamut alarm, you can preview which on-screen colors cannot be printed accurately. The colors that cannot be reproduced are highlighted. When you import or export graphics, you can embed or attach color profiles. By embedding a color profile, you can ensure color integrity, anyone viewing or printing your work will use the same colors that you used. There are advanced settings for separations and composite printers. You can link a color profile to a specific printer. When you use color management styles, you can turn off color management or optimize the color display for different outputs. Source.
