Earlier today I gave CA Support feedback on this challenge.
Step 1 - Change the calculation on the attribute Overall Status on the Object Status Report - use Max(cop_schedule_status,cop_scope_status,cop_cost_eft_status), and you will need to change the Display Mappings ranges to be 10-10 Green, 20-20 Yellow, 30-30 Red.
Step 2 - You will then need to undertake similar changes on the following portlets - Status Report Indicators, Status Report Listing
Step 3 - You will need to undertake similar changes on the following JasperSoft Reports - Project Status Report, Project Storyboard.
My feedback to CA Support was why doesn't Portlets and JasperSoft use the view odf_cop_prj_statusrpt_v which includes cop_overall_status_color (or similar) where the view contains what 'color' is returned by the calculation so the change only has to be done once.
