In the early days, they used to have the RAC quack wave flags around at Belgrade Square.
The only time I have ever had an issue with colour vision was on the footplate of a train. On a particularly straight and level stretch of track outside York the block signalling could be seen numerous sections into the distance. The driver could see that the furthest signal was green - I could see the light but couldn't tell its colour. Not being able to identify a 24w bulb at about 5 miles has never really caused me a problem!

I agree whole heartedly.. It rarely causes me an issue. Again it is probably down to some quack re-writing a set of old rules without much thought for the real world.
