When creating new features with a boolean operation, the feature is not getting
set to the correct color.
There are two preferences that define the feature colors:
Preferences -> Object, and edit the "Solid Body" color to something other than
what is currently set.
Preferences -> Modeling, and edit the "New Face Properties" to "Part Default".
Select the correct options to what you want as the results.
