hey peter,
this problem has an "old history"... just visit this threat:
Color issues in Mountain Lion with Acrobat Pro
the only solution for this problem at the moment is to use iccir/ColorFaker · GitHub
but it only works for OS X 10.x – 10.9. i just upgraded to 10.10 and had to see, that it doesn't work anymore under yosemity :-(
best,
ivo
