In one of RMI's P3s, I used the red and blue elements of some RGB LEDs in
place of the red/green LEDs.
Duncan should be able to tell us if that helped his colour-blind bandmate.

The LEDs I used had 6 legs - 1 red anode, 1 green anode, 2 blue anodes and 2
cathodes.
It was a simple job to clip off 3 legs, leaving just the red, common cathode
and blue legs.
I can do this as a special order in future if required.
It'll cost a bit more though - the RGB LEDs are about a lot more expensive.
