Can't believe nobody mentioned colourblind readers. I'm not into the political correctness thing at all but if you want to have as broad an audience as possible, this is the way to go.

From "The Elements of Statistical Learning":

Our first edition was unfriendly to colorblind readers; in particular, we tended to favor red/green contrasts which are particularly troublesome. We have changed the color palette in this edition to a large extent, replacing the above with an orange/blue contrast

There's a lot more to be said though, here's a helpful article on the subject:
