Makes sense to me. I don't suffer from deficiency, but Rigil does. Apparently red/green deficiency is common to 10% boys.

Hi,
Yes, the green GO light is an aqua with blue in it, since very rarely do people have deficient clour vision in all those wavelengths. It does not help to put orange with red.
The amber light is more of a problem I found, since I could not tell a very dirty amber light from a new bright red one.
However I could pass the driving test on the position of them.
For those interested here is a list of the intersections where you might encounter me in Sydney:
King Georges and Hillcrest
Boundary and Roberts
King Georges and Forest
Boundary and Forest
....more later
Cheers
