Try this:

• Copy the original histogram into a new object
• zero out all bins of the copy except the ones defining your "exclusion area" using SetBinContent(),
• draw the original histogram,
• call SetFillColor(N) on the copy or otherwise change how it appears
• draw the copy on top of the original by calling Draw() with the "SAME" option.
