 With deuteranomalous color blindness (the most common kind, 6% of males),
 some of the colors used on metrics graphs are hard to tell apart.

 In https://metrics.torproject.org/network.html#relayflags, (reddish?)
 "Guard" and (brownish?) "Fast" are almost the same, and (greenish?)
 "Running" is close to those two. "Exit" and "Stable" are also similar, but
 not too hard to distinguish.

 In https://metrics.torproject.org/network.html#platforms, "Linux" and
 "Darwin" look the same at a glance.

 In https://metrics.torproject.org/network.html#bwhist-flags, "Guard only"
 and "Middle only" are similar, likewise "Exit only" and "Guard & Exit."

 I attached before and after images from
 http://www.vischeck.com/vischeck/vischeckImage.php of one of the graphs. I
 find the simulation to be accurate, in that the colors before and after
 look the same.

 You can see how all the graphs look at once by going to
 http://vischeck.com/vischeck/vischeckURL.php, entering
 {{{https://metrics.torproject.org/network.html}}}, submitting the form,
 and then clicking "Deuteranope simulation." It generated me a page at
 http://vischeck.homeip.net/uploads/134317381427149/, but that might be
 cached temporarily.
