Hi,
GNR coaches have a semi elliptical roof, and square panels made by strips over the teak body.
Alas the Bachmann coaches are nothing like the GNR or the ECJS coaches; I have some drawings and the book on ECKS stoch which is the long distance carriages for such services as London - Edinburgh. The IP coaches though much shorter are to the 'tradititional' UK carriage design, and are in design very like North Eastern Railway coaches to which the GNR connected at York, they are maroon in colour after an early two colour livery.
A photo of an NER clerestory bogie coach and a 4 wheel one as well is at

The Bogie Clerestory has a very faded/weathered colour! The NER had 6 wheel designs as well, though bogie coaches may be better as making 6 wheel chassis are a bit difficult, to get to run well, especially on our necessarily sharp curves.
There are two GNR coaches in the collection of the Vintage Carriages Trust at the following link for a list of their vehicles -

From that you can 'click on' the links to a photo.
The roof colour could also be a light red oxide.
For a really first class vehicle the Bluebell railway have the GNR Directors Saloon, which is a clerestory that can be seen at

That is a start.
Yours Peter
