I'm having problems with a Mac OS-X (10.3.9) displaying lurid colours on the desktop or when viewing a PDF in either Adobe Acrobat or Preview.
When I choose a solid colour for the desktop, although the 'thumbnail' colour swatch appears correct, when the colour is picked the desktop turns an overly bright, highly saturated version of the same colour (for example Lavender appears as a bright pink).
Equally when I view a PDF file, the colours are extremly bright and highly saturated even though the white background appears fine. The rest of the OS (menus, icons, images etc) are unaffected.
I have tried calibrating the monitors, repairing disk permissions, creating a new user account and running applejack but the problem remains - any ideas much appreciated!
