Hello,

I just installed the latest stable version on my MacBook and I noticed that the colors in the interaction are different. The Error messages are printed in white so they are not visible.

I just noticed the exact same thing and was about to post. You can see them in dark mode, so that might be a workaround if you don’t mind dark mode.

There was a [commit that fixed Python console colors](https://github.com/Slicer/Slicer/commit/ab51796fd3bf42a9f38fd82a40e0ac2ca4781e27) after the 20200930 release. Could you please try if colors look good in the latest preview release?

I have a recent build (couple of days old?) and the colors look fine in that, so presumably the latest preview is okay too.

Thanks!

Thanks for testing. Currently, we don’t plan to have a patch release for Slicer-4.11 but we’ll see what else comes up and how long does it take to make Slicer-4.13 functional (and release Slicer-5.0).

As a quick workaround, if you don’t want to switch to dark mode for everything, you could use:

```
slicer.util.mainWindow().pythonConsole().backgroundColor = qt.QColor(0,0,0)

```

to just switch the python console to black.
