Hi there ... till now the following ist the only »help« to bring color management back to Acrobat - not testet yet with the latest Yosemite:
There is a workaround (on Mavericks - but it should be the same on Mountain Lion) with Color Faker (http://github.com/iccir/ColorFaker) which seems to work till a fix will come ...
Start Color Faker and switch it on (important that no Adobe Software is running at this time) - start Acrobat ... go back to Color Faker and switch it off ... since you dont close Acrobat it has the Fake Color in its cache and the preview of the color is as it should.
The rest of the Adobe Suite seems to work normal (Without any guarantee! Please check it out by yourself and post here if you find another issue in this workaround - thanks) ...
Regards
Jörg
