Dhineshkumar S cb41f39045 Disable custom color selection when Fill Mode is Body Background Color 
Currently, the system allows custom color selection for the Fill Color
property in the Properties toolbar even when Fill Mode is set to Body
Background Color via the Properties window. However, this does not update
the color to match the Body Background color. To fix this, custom color
selection for Fill Color will be disabled when Body Background Color is
chosen.
