I think there might be an issue with the Crimson drivers and the colour controls. I would recommend rolling back to the latest Catalyst driver to see if this restores the functionality. If it does, please report the issue here.
Same problem here.....
What I did is use all the default settings and restart my laptop and it worked "BUT" it is not permanent every time you open your AMD graphics property it will reactivate and still you cannot deactivate it ( Reactivate AMD color button still cannot be click). You have to restart your laptop again.......
Im also looking for a permanent solution....
Go to start menu search and look for 'color management'. Go to advanced tab and choose 'Change system defaults' at the bottom. Go to advanced tab again and check 'Use Windows display calibration'.
windows management will work.. the greyed button you see will be ungreyed.
and you can add icc profiles.
