You normally model in Monochrome mode and then apply materials to the forms.
So having a neutral color for the right-way-round faces seems a sensible choice.
A bright back color shows up anyway.
There is a FixReverse... tool that reverses incorrectly 'colored' faces, even if their backs have a material too - the default tool assumes you have only applied it to the back !
Use the 'force' tool and it should flip the face and materials ?
NOTE:
If the material is always the same on both sides of a face, then you can simply view in Monochrome, select the problem faces [Tip: use Ctrl to add to the selection, and Shift+Ctrl to remove items from the selection] then use your shortcut key to Reverse the faces en mass.
When I say 'context' I mean where the entities are...
So faces can be in the model itself or within a group or a component which is placed in the model, or even within another group or component.
A group or component 'container' is like a separate SKP within the model...
You can edit the 'container' using the context-menu or by doing a double-click on it.
Then you are in the container's context and can edit those faces in there.
There is no need to 'explode' containers.
'Containers' will separate geometry etc so have important uses...
