Present now, thanks.

Seems to have no effect, guess the distro perf binary is too old for
that (RHEL-6).

That works. I don't want turn off the tui altogether though, I actually
like the interactive expanding+collapsing of the call graphs. I just
want turn off the colors.
perf_color_default_config() in util/color.c seems to lookup a "color.ui"
config variable. Can I set that somehow? Tried ui= in a [color]
section -- no effect.

Bad idea IMO. Setting only one of foreground+background gives pretty
much unpredictable results. My xterms have different background colors,
the ones with a root shell happen to have a (dark) red background.
Which results in red-on-dark-red text. Not good.
I'd strongly suggest to either set both background and foreground to
default or to set both to a specific color. When doing the latter make
sure the colors have enougth contrast so they are readable.
cheers,
Gerd
