Yes: go to the face name and press RET.  You will be presented with
the Custom buffer where you can customize this face.

The face name, btw, is the first part: `compilation-info'.

One way is to use defface to have the face inherit from `default'.
See the examples in the various *.el files (search for ":inherit").
