Every basic data type is stored in Base module, color is standing out as
one that does not. Moving it to Base opens possibilities to integrate it
better with the rest of FreeCAD.
Add missing UI elements to support per face transparencies:

Dialogs to view the Appearance and Material properties of an object
These inspectors are intended to be used when debugging Appearance and
Material issues in a model.
The Appearance inspector displays the appearance properties of an
object. This will be more useful once PR 13792 is merged which migrates
parts to use ShapeAppearance instead of DiffuseColor. This shows each
of the appearance properties per face for the object.
The Material inspector shows the material, models, and properties
assigned to a model. It displays useful debugging information such as
the UUID and file paths associated with eacch of the items. This is
useful when finding and resolving model conflicts.
The material inspector now gives the option of copying the information
to the clipboard.
