I'm not sure if this is the right topic, but its the closest I could find.

I'm using the Office2007Blue theme for my Infragistic ribbons, grids, etc. in  an application I am developing.  The blue used by Microsoft is a different shade than the blue used in my logo and website.  I'm wondering how I would go about trying to modify the Office2007Blue theme to a different shade of blue.

Is this a reasonably doable task?
