First, you should always make changes in a child theme, so they don’t get over written when the theme is updated.
Second, of course. CSS rules can be *very* tricky (because they provide so much flexibility and control). Try a rule like this:
#mvp-content-main p.sbg-header-status {
color : green;
}
It will probably take a bit more work, but this should get you started down the right path.
