Yup,  which is why is was so surprised to see the device encoded

Yup, I've had bug reports asking for gcm-picker to find the nearest
pantone color from a spot measurement. We can't do that without the
legal team having a heart attack.

If you've got a link I would appreciate the background reading.

Yup, I'm a little cautious about using standards from XRite, now that
Pantone has acquired them. If it's an ISO standard, then of course it
makes sense as an interchange standard.

Great, thanks. At the moment I've created a test "X11 named
colors.icc" file (using the newly created cd-create-profile) and am
now adding NC support into gcm-viewer.
