+      Unfortunately, many vendor-supplied ICC profiles do not include the
+      information required for whole-screen color correction.
+      These profiles can still be useful for applications that can do color
+      compensation, but you will not see all the colors of your screen change.
+    </para>
+    <para>
+      In order to create a full profile, you will need to use a special
+      calibration device called a colorimeter.
