In Windows 95 and possibly other operating systems, an ICM (Image Color Matching) file contains a color system profile for a particular application or device such as a color printer or scanner. This profile is matched to a common profile that in turn can be mapped to other device's individual profiles. This allows the color system used by one computer device to match the colors used by other applications and devices on the same or other computer platforms. A profile commonly adopted by some programs and devices is the Kodak Professional Color System profile. An ICM file usually carries the suffix ".icm".
Microsoft, Apple, and Adobe are among the manufacturers who adhere to the ICC's color profiling system.
