I don't think it's acceptable to output unreadable color combinations 
(red on dark red, etc.) in any case, so we should add some safety 
mechanism that detects bad color combinations and a fallback, static 
color scheme.

I like the current way how perf top/report adapts to the xterm color 
scheme. I use it both on dark and white backgrounds and it's easy to 
mistake it for --stdio output - which is good, a good TUI should 
blend into the console's color scheme. So i think we should keep that 
and just detect the few cases where it results in something 
unreadable.

Thanks,
