Hi all,
It's becoming way harder than it really is. There are only 2 colours of trim that were released in VS and that being the Grey and also the Blue.
So it's one or the other and with yours being an Esteem I think you'll find it being the Grey interior as I'm sure there was no Blue trim offered in Esteem and Acclaim variants. Without getting my "Fiche reader" out again I can't confirm precisely as the Genuine Holden Workshop Manuals don't have a section about Trim colours written, but it's not like there are 20 different colours.
VR had 3 colours that being the same Grey and Blue along with a really nice beige, but the Beige was deleted for VS and streamlined down to the two colours only.
One thing I will add though and that is that there were very slight variations in the texture of the two colours which was just one of those production quality control issues that came about as Holden by this stage were no longer making all the plastic trim pieces and as such having parts supplied by Contracted Manufacturers.
