iWork 09 colour problem

What version of Pages are you using. Many users are finding problems with the iWork apps in Snow Leopard due to not having the latest updates as of the September 28 installed. For iWork '08 that is Pages 3.0.3 & Numbers 1.0.3. For iWork '09 it's Pages 4.0.2 & Numbers 2.0.2. iWork '09 has since had update 3. I don't use Keynote, but it should also be updated. If you're not running the latest versions & Software Update says your software is up to date, make sure the applications are where the installer initially put them. The updaters are very picky. If the location is not where the updater is programmed to look or if the folder doesn't have the name the updater looks for, it will not work. The applications cannot be renamed or moved. They must be in the iWork '08 or iWork '09 folder in Applications. That iWork folder must be named iWork '08 or iWork '09. If it doesn't have the '08 or '09 Software Update won't find them & the updaters won't work.

If you used Software Update to update Snow Leopard, got to Apple's download site & download & install the combo update. It can often fix some things not fixed or broken with the delta update. There is an issue with Hoefler Text in Pages that is fixed by updating to Snow Leopard 10.6.2 using the combo update.
