1. set diagram symbol "EnableEmbossEffects = 'true'" and use 'EffectsProvider'.
I tried change the color to 'white' using 'Shape' function.
But In this case, becasue of grey color effect, it failed to change color to white.
Please tell me how to change diagram symbol color to white in this effect condition.
If you can't suggest normal method, I want to know how to use 'r,g,b combination' to resolve thi problem.

2. When I opened diagram once saved, the setting-value was not exsactly same as that saved.
It seemed 'EnableEmbossEffects' value was not saved.
Is there any solution to resovle this problem?
