Description Simon Huerlimann 2016-07-26 21:16:58 UTC 
When using the 'solarized' theme, text output that uses the ANSI escapes for gray is not visible. it seems to use the same color as the background color.

It is okay with all other themes, including 'solarized light'.

It seem to be the same on "'Solarized' Color Scheme on Ubuntu Gnome 16.04" so the issue might be in some share upstream code.

Please see https://github.com/mattbrictson/airbrussh/issues/84 for some screenshots and more information.

Reproducible: Always

Hi, I'm from the Bugsquad team and we are triaging bugs on Konsole today.
Thanks for reporting the bug.

Application Version: 17.12.3
KDE Plasma Version: 5.12.6
KDE Frameworks Version: 5.44.0
Qt Version: 5.9.5

I took this steps to reproduce:

1- On Konsole configure the theme to "Solarized". (The dark solarized)
2- Launch python3 on Konsole.
3- Based on this test on SO (https://stackoverflow.com/a/39452138/6389248), enter the code below.

> CRED = '\33[90m'
> CEND = '\33[0m'
> print(CRED + "HELLO" + CEND)

4- It should print an empty line.
5- Now configure Konsole to Breeze theme.
6- The message now should be seen.

7- On the same session on Breeze theme, update the CRED value. 
> CRED = '\33[30m'
> print(CRED + "HELLO" + CEND)

8- The new message is invisible on that theme.
9- Change to solarized theme and you'll see the message barely visible.

Conclusion

I can reproduce the bug but I think it's inevitable to happen on any theme, i.e. grey characters on the same grey background will never be seen.

I'll change the status to INTENTIONAL because I think the behaviour of the application is as expected.
