The constant AlecRabbit\Spinner\Extras\Color\Ansi4Color::COLORS was not found. Maybe you did not declare it correctly or list all dependencies?

        }
        return self::$colors;

The expression return self::colors could return the type null which is incompatible with the type-hinted return array. Consider adding an additional type-check to rule them out.
