<title>Can I share my color profile?</title>
<p>
Color profiles that you have created yourself are specific to the
hardware and lighting conditions that you calibrated for.
A display that has been powered for a few hundred hours
is going to have a very different color profile to a similar display
with the next serial number that has been lit for a thousand hours.
</p>
<p>
This means if you share your color profile with somebody, you might
be getting them <em>closer</em> to calibration, but it’s misleading
at best to say that their display is calibrated.
</p>
<p>
Similarly, unless everyone has recommended controlled lighting
(no sunlight from windows, black walls, daylight bulbs etc.) in a
room where viewing and editing images takes place, sharing a profile
that you created in your own specific lighting conditions doesn’t make
a lot of sense.
</p>
<note style="warning">
<p>
You should carefully check the redistribution conditions for profiles
downloaded from vendor websites or that were created on your behalf.
