Unity Preferences' Large Heading Font

I wonder what’s the style behind these large headings in the “Edit/Preferences…” window. Might find it useful to recycle it instead of making my own.

See this “External Tools” heading as a reference:

Check out the PreferencesWindow class. Looks like sectionHeader is just a modified style based off of EditorStyles.largeLabel. Looks like you need to make your own if you want to match that specific style.

EditorGUI.LabelField?

You can apply your own style to it including changing the font size and color.
