The example indeed shows some of the problems with using gray scale. But:
1) The curves are too close anyway; additional charts with better 
resolution/limited cutout,... seems warranted, in particular if the 
point of the graphs wasn't just "it's 12 of A and one dozen of B".

2) At least for those with color view, color would have improved these 
examples tremendously.

3) In the end, because some people don't have any eyesight, there has to 
be text to explain all the salient details anyway.

I don't mind the production staff taking their time in adopting 
color/grayscale/... But I'm quite worried of putting "no color" or "no 
grayscale" into the current document, because I don't want to risk it 
taking another 10 years to get there. We are already very far behind.
