Thank you for your reply.
I tried all of your suggestions, but ran into roadblocks each time:
>> 3. in the righthand pane right-click and select New and then Random Color Ramp
I can not select New... this option is greyed out. I can only select Copy. How do I paste this into my style? Will it paste the same colors for the categories every time?
>>You can also edit an existing color ramp in the layer symbology dialog by right-clicking on the field that shows the color ramp and selecting Properties. If you edit it this way make sure you right-click on the field that shows the color ramp and select Save to Style right after you have edited it. Otherwise ArcMap doesn't save the style.
I tried this as well, and I can save the style, but when I set up the pies for other layers, it doesn't pull up my saved style. When I select the same color ramp for all the layers, I get the same colors, but they are assigned to different categories.
Any other suggestions?
Thanks!
