Hi rdavies, TBH I'm surprised to hear that.
If you have a GDI Plus 4 (2014-2020), it'll have this gauge set:

The earlier port injection Duratec Plus 4 had different gauges that were definitely produced by CAI, and I strongly suspect the later GDI Plus 4 only received different gauges because they needed to work over the GDI ECU linked control area network (CAN). I don't have the production numbers for the GDI Plus 4 but over the six years I would assume it would have been in the range of 3,000 to 5,000 cars tops, so whoever made the gauges must have been up for creating a relatively low volume run.
As far as I'm aware, there really is only one UK low volume automotive instrument manufacturer with the capacity and capabilities to produce a full gauge set in such volumes, and that's Caerbont Automotive Instruments (CAI). Perhaps in 2014 CAI didn't have the knowledge and capabilities to produce CAN instruments, however, they do seem to have CAN capability now as they are showing CX gauges on their website and I'd be amazed if these instruments don't communicate over CAN with what must be a modern BMW sourced ECU and CAN based loom?
If Caerbont Automotive Instruments (CAI) really didn't produce the GDI gauge set, the question to ask is 'who did'? From there you can approach them to see if they'd help with your gauge face colour change project? If that results in a dead end I'd talk to SpeedHut in the States who offer a custom gauge service.
https://speedhut.com/Just be aware you will likely be better off keeping your existing gauges and just changing the faces rather than buying new gauges because your gauges are almost certainly CAN paired to your CAN communicating ECU, saying that, it looks like SpeedHut have developed a clever CAN BUS solution, as explained here:

https://classicsparesengineering.co.uk/Under the title 'Classic Gauge Face Reprinting' they state the following:
"Have the original face of your classic car gauge restored. We can also print a brand new gauge face with custom colours and digits"Classic Spares Engineering are based in Lanarkshire and look like your best option to me

If not, maybe try these people who claim to offer a similar custom gauge face service:
