I, too, am r/g colourblind, and don't know anyone else who is. Multicolour LEDs have always been a problem for me, and my gf can't believe that I can't read them... I also have issues with the UI of one of the apps I use regularly (wavelab) as the master section on/off is the wrong shades of red and green, so that's a problem.

Thanks to everyone for posting in here about it - I no longer (at 49!) feel like I'm the only one in the world who has this issue with LEDs in particular.
