Use VBA to modify "Pie" shape/color

In a previous thread (https://www.experts-exchange.com/Software/Office_Productivity/Office_Suites/MS_Office/Excel/Q_28184618.html), both experts byundt and rorya have provided fanstastic assistance with a ~90% solution.

However, as the thread grew in length -- and it eventually turned into somewhat of another subject -- it makes sense to now start a new question now.

** Break **

Please see attached XLS for details.   Here's the scoop on it.

1. On tab "Shape", there are four data entry cells (E15:E18).
2. The "Notes" area (starting in cell K14) illustrates the four "pie" shapes.  Their angles are currently driven by two (2) adjustment variables in the VBA code.   The angles/shapes work great... no additional work is required.
3. Right now, only one shape/pie is shown in cell area E1 through F4 (approximately)

What's needed:
- Zone 1 should be linked to bottom left pie (currently red).
- Zone 2 should be linked to bottom right (currently in yellow)
- Zone 3 should be linked to top right (currently in yellow)
- Zone 4 should be linked to top left (currently in green).

(Btw, order of these can be changed... I chose counter-clockwise right now...).

- Basically though, I'd like to display all four shapes together... mimicking an oval/egg-shaped display.  
- The top two pie should be slightly larger (maybe even twice as large) as the bottom two shapes.  
- Most importantly though, the values in E15:E18 should drive their individual colors.   So, basically following a stopo-light principle.

Again, please see attached XLS for details.

Does anyone know how to accomplish this?

Thanks,
