Change all Jupyter notebook background colors in PyCharm to white

Question

I've somehow changed the appearance of my PyCharm environment and now because my screen is not very bright I don't see a thing when it's sunny day.

It looks like this now:

So, I thought that changing theme from Darcula will help:

But the result is even worse:

I know that it's impossible to change output color from black but I think all other could be feasible. Could you give me steps to revert to default apperance? Normal white notebook would be best. Thanks.

Answer 1

In PyCharm 2019.1 to change the background color of the selected cell of a Jupyter notebook I did PyCharm > Preferences > Editor > Color Scheme > Jupyter > Selected Cell and unticked Background

Answer 2

For PyCharm 2019.1 on macOS HighSierra 10.13.6, I observed, that changing the theme of appearance to "Light" helps out. I remember, this used to be named "Default" in older versions of PyCharm. (Thereto, just as you described, go to Preferences -> Appearance & Behaviour -> Appearance, and select the appropriate theme in the drop-down menu.) However, the changes did only apply to jupyter notebook after closing and reopening the project.

In short: Restart or Reopening the Project after applying the changes should help.
