Many thanks for the replies to my query, I also have the plate on the passenger side B door pillar with four numbers set vertically below the Vin number but was unable to discover if any of these related to the paint code.
The bottom two 855 and 835 I thought might be the code number but a previous search elsewhere gave me NH880 M (Shining Grey Metalic.) I have now gone back to Honda as this colour is used on the current production range. Thanks for everyones assistance.
