You can set an environment variable globally if you want to avoid the
default behaviour. See

https://www.boost.org/doc/libs/1_69_0/libs/test/doc/html/boost_test/utf_reference/rt_param_reference/color_output.html

The variable BOOST_TEST_COLOR_OUTPUT is there for your need.

Right, so your problem is rather the color scheme of Boost.Test that is
not playing well with your color scheme. It is true that I did not
adjusted the background and I made the hypothesis of the default one.

I respectfully disagree with this statement. I personally like having
color outputs, and combining this with log levels let me parse a big
amount of information/logs significantly faster.

I am fine with that. I still consult this list, although in a less
regular manner.

If the variable BOOST_TEST_COLOR_OUTPUT is good enough for you, or if
you want an improvement, let me know.
