Some metrics colors are hard to distinguish with color-deficient vision

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.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
