Default Colors in Microsoft Office Excel Chart OLE Objects

I am using a Powerpoint 2007 add-in that works specifically with Microsoft Office Excel Chart OLE Objects ("Insert > Object > Microsoft Office Excel Chart"). I have setup a custom color pallet in both PowerPoint and Excel that is used as the default in new PPT and XLS files. However, when I insert a Microsoft Office Excel Chart OLE Object into a PowerPoint file, this custom color pallet is not used as the default. Instead, the colors revert back to the "Office" pallet. Does anyone know why these embedded objects don't use the color pallet that I have defined in the "XLSTART\book.xltx" template? Even better, does anyone know how I get the default color pallet to be anything other than "Office" for these embedded Microsoft Office Excel Chart OLE Objects?

Have you tried saving the chart as a chart template (crtx) ?

Thanks for the reply. I tried your suggestion and it worked, but I'm wondering if there is a solution that has a more global effect. The CRTX option works on a chart-by-chart basis, but I have presentations with 30-40 charts embedded in them, each of a different size and type, so creating and using that many chart templates would be difficult to manage. Is there a way to simply change the colors in the "Office" color pallet? If I could change them globally I think that would solve my problem. User generated image User generated image
Apperently, Excel and Powerpoint uses color themes, but they are not linked !

E.G. when excel uses an arbitrary excel theme, then copies a chart which is pasted in powerpoint, the active powerpoint theme will be applied to the chart.
It seems that the themes themselves are linked, when I change a custom theme in powerpoint, the corresponding theme in excel is updated as well.

Thus the problem seems to be that powerpoint does not default to the correct custom theme. Can you verify that when you manually select the correct custom theme, charts are pasted as you expect them to be ?

If not, you might want to think about pasting charts as pictures :
click on "Paste special", select "Bitmap" (or any other picture type)

When they first get inserted into the PPT the colors are correct. I have the same theme selected in PPT and Excel, which appears to be working. However, when I run a procedure that updates the chart with new data the colors in the chart revert back to the Office theme. Unfortunately going the picture format route is not an option, as these charts are dynamic and will continuously be updated with new data.
