I believe property is level 3. Quoting the (emacs) manual:

Level 1
     This level usually fontifies only comments and function names in
     function definitions.
Level 2
     This level adds fontification of keywords, strings, and data types.
Level 3
     This is the default level; it adds fontification of assignments,
     numbers, properties, etc.
Level 4
     This level adds everything else that can be fontified: operators,
     delimiters, brackets, other punctuation, function names in function
     calls, variables, etc.
