What is it you've got against the colour-blind? Really, such disablist attitudes have no place on this forum.
(1) Firstly, one does not say 'the colour(-)blind', but 'colour(-)blind people'. That's political correctness for you right there.
(2) Colour(-)blind people will be able to take note of the different positions of the respective signals on the signal head. As a rule, they generally don't have much of a problem with the operation of automatic traffic signals.
