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, (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, "Linux" and "Darwin" look the same at a glance.

In, "Guard only" and "Middle only" are similar, likewise "Exit only" and "Guard & Exit."

I attached before and after images from 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, entering, submitting the form, and then clicking "Deuteranope simulation." It generated me a page at, but that might be cached temporarily.

I'm using ggplot2's default color scale for most graphs. I'll try out other color scales and check them using the URL you posted. Thanks!

Please check out if works better now.

Karsten, you are my new favorite person. Thank you so much for taking my request seriously.

These graphs that used to be difficult are perfect now:

I still have a lot of trouble with the #009e73 (FreeBSD) and #999999 (Other) in Colors close to gray, that differ only in the red channel, are hard to distinguish. Could one of them be black or a darker gray? #333333 works well for me locally.

Glad you like the new colors. :) Changed "Other" to #333333.

Sounds like that's all there is to do for this ticket. Closing. Please re-open if necessary!
