Express: Can the error handling middleware accept an argument to pass to your templating language like pug?

So here is what I am trying to do...

I have a website with a front end and back end which both might need to handle errors.

I want to display my error page with the styling dynamically... so if it is the front end, style it one way and if it is the backend, style it another.

Is there a way to have the middleware of express pass a paramater to pug so that I can conditionally style my error page?

here is my error handling setup in my app.js file:

// catch 404 and forward to error handler
app.use(function(req, res, next) {
    var err = new Error('Page Not Found');
    err.status = 404;
    next(err);
});

// error handler
app.use(function(err, req, res, next) {
    // set locals, only providing error in development
    res.locals.message = err.message;
    res.locals.error = req.app.get('env') === 'development' ? err : {};

    // render the error page
    res.status(err.status || 500);
    res.render('error');
});
