Out of curiosity, are there reasons why this shouldn't be solved at the browser or even OS level? The only reason I can think of is that solutions at the app level makes it possible for people to refer to a blue line, red bar, and whatnot and it means the same for everybody. But if we need many color profiles anyway because there are many kinds of color blindness, perhaps we should just make the labels pop out or have fewer series per graph (so that we can just refer to these graphs instead of individual series in them).
