color difference between canvas and download/reproduction

[benmaier]

So here's a weird one: While playing around with colors and reproducibility, I've noticed that my matplotlib-figures looked brighter than what I've seen on the screen. And apparently that's true, even though the downloaded figure has the right colors again:

funnily enough, the grey node stroke did not change between display in the browser and matplotlib/downloaded png. Ideas what's happening here?

oh, and the background color is also plain white in all of them

Pretty sure I'm not colorblind, but I actually can't tell the difference :O
