RGB
Determines the RGB color space of the application. In general, it’s best to choose Adobe RGB or sRGB, rather
than the profile for a specific device (such as a monitor profile).
sRGB is recommended when preparing images for the web, because it defines the color space of the standard monitor
used to view images on the web. sRGB is also a good choice when working with images from consumer-level digital
cameras, because most of these camera use sRGB as their default color space.

Adobe RGB is recommended when preparing documents for print, because Adobe RGB’s gamut includes some
printable colors (cyans and blues in particular) that can't be displayed using sRGB. Adobe RGB is also a good choice
when working with images from professional-level digital cameras, because most of these camera use Adobe RGB as
their default color space.

CMYK
Determines the CMYK color space of the application. All CMYK working spaces are device-dependent,
meaning that they are based on actual ink and paper combinations. The CMYK working spaces Adobe supplies are
based on standard commercial print conditions.

Gray (Photoshop)
Determines Grayscale color space of the application.
Spot (Photoshop)
Specifies the dot gain to use when displaying spot color channels and duotones.
Adobe applications ship with a standard set of working space profiles that have been recommended and tested by
Adobe Systems for most color management workflows. By default, only these profiles appear in the working space
menus. To display additional color profiles that you have installed on your system, select Advanced Mode (Illustrator
and InDesign) or More Options (Photoshop). A color profile must be bi-directional, that is, contain specifications
for translating both into and out of color spaces in order to appear the working space menus.

Note: In Photoshop, you can create custom working space profiles. However, Adobe recommends that you use a standard
working space profile rather than creating a custom working space profile. For more information, see the Photoshop

About missing and mismatched color profiles
For a newly created document, the color workflow usually operates seamlessly: unless specified otherwise,
the document uses the working space profile associated with its color mode for creating and editing colors.
the document uses the working space profile associated with its color mode for creating and editing colors.
However, some existing documents may not use the working space profile that you have specified, and some existing
documents may not be color-managed. It is common to encounter the following exceptions to your color-managed
workflow:
documents may not be color-managed. It is common to encounter the following exceptions to your color-managed
workflow:
•
You might open a document or import color data (for example, by copying and pasting or dragging and dropping)
from a document that is not tagged with a profile. This is often the case when you open a document created in an
application that either does not support color management or has color management turned off.
from a document that is not tagged with a profile. This is often the case when you open a document created in an
application that either does not support color management or has color management turned off.
•
You might open a document or import color data from a document that is tagged with a profile different from the
current working space. This may be the case when you open a document that has been created using different color
management settings, or a document that has been scanned and tagged with a scanner profile.
current working space. This may be the case when you open a document that has been created using different color
management settings, or a document that has been scanned and tagged with a scanner profile.
In either case, the application uses a color management policy to decide how to handle the color data in the document.
