keep workbook's current colors, but update color palate??
 

I created a workbook using a particular color palate I created.
I would like to import 2 sheets from a different workbook that uses a
different color palate.
When I do this, the colors in new sheets I imported get changed to the
colors in the new workbook's palate.
Is there a way to change a workbook's color palate, BUT keep the current
colors in a workbook the same??

Thanks!
