There isn't a default function that can do this, but it can be done with a UDF.
To add this to your worksheet, in Excel hit Alt+F11, Insert -> Module, and paste this code in there.
This gives you a new function called ColorFunction. The parameters are =COLORFUNCTION(a cell with the color you're looking for, the range, True for SUM or False for Count)
So, in your workbook in F2 I put:
=ColorFunction($C$6,[@[Job Name]],FALSE) since C6 is orange, and I want a count of the cells not the sum of their values.
Then I just dragged that formula down and over.
