Re: Be careful about differentiating by colour
I dont know if there is such a thing as sudden-onset colourblindness, but I believe most colour blind people will have lived with the condition all of their lives, and entered the adult workforce with management techniques developed from living with the condition.
This would probably include reading labels. Which does mean adequate labeling is essential.
Just because something is strange and outside your own experience, doesnt mean it isnt routine and everyday for others.
I am not saying its easy, but people cope.
