Python defaults diverged in several places: built-ins used the predefined magenta, __init__/__doc__ used function/self colours, instance fields the property colour, f-strings and byte strings the generic string colour, and the PEP 695 type keyword was uncoloured. Python now has its own tokens for built-ins, predefined definitions/usages, f-strings and byte strings; instance fields follow identifiers; type is a keyword. Unused parameters (not reported by Pyrefly) are greyed by a scope-aware local check that skips self/cls/_ names and signatures dictated elsewhere: stubs, @abstractmethod/@overload/@override, dunder methods and methods of classes with bases.
