Setting Entity Color via Model Tree View needs to be consistent with 3D Context menu
Setting an entity color via the 3D View's context menu and via the Model Tree View have different defaults when the entity doesn't initially have an explicit color assigned to it:
Via 3D View Context Menu- Value is 255 and Alpha is 255 Via Context Menu in Tree View - Both Value and Alpha is 0
The Context menu method should behave like the 3D View.
