Swift Champagne paint colour code

Good afternoon.

We've recently got back from a lovely time in the Gower, but during which we had an argument with the coping stone on a masonry gatepost that jumped out at us, resulting in a tiny dink that's gone down to bare metal. I'm trying to find the paint code, but it's not on any door pillars, or in any documentation I can see, nor does the dealer (Brownhills) know it, and they said Swift don't know it either!

It's a Swift Champagne, basically a Swift Select in a Brownhills special colour, described as "Champagne" in the documentation, but no code given. Brownhills' advice was to try to get Halfords to colour-match it. I thought that a bit off, given the money we paid for the van, in a colour of Brownhills' own choosing (not our own first choice, but it was all that was available at the time!)

Anyone had a similar issue or that can provide advice?

Many thanks!
