A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
Unfortunately, there hasn't been any more discussion. I think John K is right, in that it has more to do with Mac color profiles conflicting with microsoft powerpoint. Which isn't something I feel like messing with, solely to appease powerpoint.
The only semi-solution i've found is to change each color individually, meaning change the R value, save. Change G value, save. Change B, save. Be sure to do this to the template master colors, so you're not stuck repeating this process with every headline.
hope it helps, and good luck, I understand your hell. :)
