[users at bb.net] How to increase contrast in log viewer?

[Dan Kegel]

It's kind of a pain to have to highlight the log window in order to read it.

I posted this question to IRC just now:

How would one go about increasing the contrast / changing colors used
in the log viewer?
See https://github.com/buildbot/buildbot/issues/4186

(BTW I'm using a --user installed buildbot from source, so when I tried tweaking
www/base/src/styles/colors.less, I did
python3 setup.py install --user
in www/base and then restarted buildbot and looked at an old log.
Maybe I'm doing that wrong...)

Looking for a little help - via email, irc, or on that bug.  Thanks!
