Testing color management isn't hard, and we even supply some test
profiles.

<title>How do I test if color management is working correctly?</title>
<p>
The effects of a color profile are sometimes subtle and it may be
hard to see if anything much has changed.
</p>
<p>
In GNOME we ship several profiles for testing that make it very
clear when the profiles are being applied:
</p>
<list>
<item>
<p>
<em>Bluish Test</em>: This will turn the screen blue and tests
if the calibration curves are being sent to the display
</p>
</item>
<item>
<p>
<em>ADOBEGAMMA-test</em>: This will turn the screen pink and
tests different features of a screen profile
</p>
</item>
<item>
<p>
<em>FakeBRG</em>: This will not change the screen, but will swap
around the RGB channels to become BGR.
This will make all the colors gradients look mostly correct, and
there won't be much difference on the whole screen, but images
will look very different in applications that support color
management.
</p>
</item>
</list>
<p>
Add one of the test profiles to your display device using the
<guiseq><gui>System Settings</gui><gui>Color</gui></guiseq>
preferences.
</p>
<p>
Using these profiles you can clearly see when an application
supports color management.
