Too many LEDs here!

- Blue illuminating Red should work (given in text)

- Green illuminating Red I think should work (Green bandgap higher than
Red bandgap) [this is what I was alluding to]

- Red illuminating Green or Blue shouldn't work (Red bandgap lower than
other two)

- Green illuminating Blue shouldn't work (for reasons above)

- Blue illuminating Green should work (also for reasons above)

Of course, I could be making things up as I go along - it wouldn't be
the first time :E
