ICC profile is a standard format for color management information. It may appear in a file by itself, or embedded in certain graphics file formats.
Format
An ICC profile has a 128-byte header, followed by an index ("tag table") with a variable number of entries, followed by a data section containing items pointed to by the index.
Embedding
In a TIFF file, tag 34675 is used for ICC profiles. See the ICC profile specification for details.
In a JPEG file, an APP2 marker with an identifier of "ICC_PROFILE" is used for ICC profiles. See the ICC profile specification for details. Note that large ICC profiles must be split up, to accommodate JPEG's 64KB segment size limit.
In a PNG file, chunk type iCCP contains an ICC profile. See the PNG specification for details.
In Photoshop Image Resources metadata, an ICC profile uses Resource ID 0x040F.
GIF and BMP files may contain ICC profiles, but that is uncommon.
