I had to get the dark claret colour mixed up for me, when I painted the door pods for my car. You can't buy it pre-mixed. I searched far and wide.
My trimmer ended up sourcing foam backed dark claret velour for the door cards. I don't know where he got from, but he reckons it's not easy to get. Apparently it's not so difficult to find dark claret velour without the foam backing though. I actually found it somewhere online, can't remember where now
