Powerpoint change label background based on Excel Cell value

Hello,

Is it possible to change the background color of several labels to either red or green based on values stored in an excel sheet?

The PP slide will have a number of label boxes that are either red or green and a text label beside it describing what it represents. The excel spreadsheet will have a column of 1's or 0's that are changed by a user and the powerpoint slide automagically updates when the excel sheet is changed.

Any help would be greatly appreciated.

Thanks.
