I have a combo box that I've added to a Word 2010 document and have populated it already with the options - "Critical" , "High" , "Medium", "Low". Once a user makes their selection from this list, I'd like to change the font color and background color within the combo box as follows:

Critical = Red background / White font
High = Orange background / Black font
Medium = Yellow background / Black font
Low = Green background / White font

I'm sure that this is not the first time this topic has been discussed, however, I am not sure exactly how to add the code to the combo box, so I apologize upfront for the redundant thread. If there is currently code available that I can tweak to fit my color scheme, then great, some help on how to add it to the combo box would be very helpful as well.
