Back in the 1950s, when I first learned to fly, red/green colour blindedness
was of fundamental importance as ATC was communicated by the tower pointing
a red (refusal), or green (approved) light at you.
I think it then took a few decades for CASA to realise the earlier criteria
might have less significance in the days of radio!

I will pass an interesting story about those who judge color blindness.
Some years ago, whilst going for a medical examination for a racing licence
(water-skiing), I was hand-balled to the "intern" at my local GP's for a
medical. I had known the GP for many years and he was confident I would
pass, a fit, young healthy 20 something year old. The medical apprentice
took me aside, probed here, pushed there, checked this and prodded that. A
half hour went by whilst everything came out fine. Then came out the
eyecharts, low and behold I am color-blind! Red was green, yellows were
white, the whole she-bang. I was devastated, my face must have dropped a
mile. The GP was duly advised, and consoled me on the spot. I had known for
years that my father was afflicted the same way, although that mattered
not, as he didnt want to ski-race!
The GP- seeing my dissapointment- suggested we test again, winking that
there werent THAT many colors in water-skiing at speed and that I should
probably not pursue a career in electronics, as colored wires are common
and might prove expensive to get wrong. So the three of us sat down and
re-tested the sad 20 something year old, first with the lettered distance
charts (always read them on the way in, if the bottom line says "printed
by blah blah blah printing, Melbourne" and you recite that when asked for
the lowest line you can discern, you will pass, believe me), then the
colored pages.
We all rolled about laughing when it became obvious that it was the intern
that was color-blind, not the patient. Poor bugger was on his 4th medical
year and never knew.
