Creating custom RGB profiles

When designing a custom RGB profile, you can specify the gamma, white point, and phosphor settings of your monitor or RGB device.

To create a custom RGB profile:

1. Do one of the following:
• In Windows and Mac OS 9.x, choose Edit > Color Settings, and select Advanced Mode.
• In Mac OS X, choose Photoshop > Color Settings, and select Advanced Mode.
2. Under Working Spaces, choose Custom RGB from the RGB menu.
3. For Name, enter the name for the custom profile.
4. For Gamma, enter the gamma value you want to use.
5. For White Point, choose a setting.

For more information on gamma and white point settings, see About monitor calibration settings.

6. For Primaries, choose a set of red, green, and blue phosphor or primary types. This option is based on the different red, green, and blue phosphors or primaries used by monitors to display color. If the correct type is not listed, enter custom red, green, and blue chromaticity coordinates.

Note: Because you are defining the color space in which to edit images, the primaries do not have to match your monitor.

7. Click OK.
8. Save the custom profile. (See Saving and loading working space profiles.)
