 It is not possible to extract the ICC file if the colorspace is just declared into the metadata, but not embedded as a profile. In this case you can search instead into the **/usr/share/color/icc/colord/** folder for well-known ICC files installed by the **colord-data** package.
+==== Examine an ICC color profile ====
+We can use the command line tool **exiftool** from the Debian package **libimage-exiftool-perl**.
+To examine a profile embedded into an image:
+<code>
+exiftool -icc_profile:* photo.jpg

+To examine an ICC profile file:
+<code>
+exiftool profile.icc

-Some known colorspaces are: **sRGB**, **RGB**, **CIELab**. To list colorspaces supported by Imagemagick, execute the command **convert -list colorspace**.

 An **ICC color profile** is **not embedded** into the file, so the software used to open the resulting file must be aware of that colorspace by itself.
