Control Excel cell color using a function

Hello.

Wondering if cell color can be controlled using a function instead of a macro.  Specifically what I need is to turn the cell fill color yellow when a data entry error is made by a user.  Here is my existing function which is in Cell C3:

=IF(SUM(B3-A3)>0,"Error","")

In addition to displaying "Error", which it already does, I want to modify the function to turn cell C3 yellow when an Error is made (i.e. when the value in B3 is greater than the value of A3)

Thank you

Add Conditional Formatting in C3 that looks like this.

You do that by selecting "Conditional Formatting" from the "Styles" group
  1. Click "New Rule"
  2. Select "Format only cells that contain"
  3. Then in "Format only cells with" choose "Cell value" and "equal to" and in the box to the right, type "Error" (without the quotes)
  4. Then click the "Format" button, select the "Fill" tab and choose yellow
  5. Click OK twice
