Sort multiple columns in pivot

Excel 2013. This is my PIVOT table where the item labels are in tabular form. What I am trying to do is sorting as follows :

1. column 1 sort order should be Red, Amber, Green


2. Column 2 sort order should be A-Z


3. Column 3 sort order should be PCC3,2,1,0

How can I accomplish this? I tried more sort options. No use. Can this be done using excel VBA?
