Um, wait, I suggested doing the exact *opposite*. I thought that maybe 
you could change the mappings so that things asking for black would get 
white, vice versa, and so on. However, you have to be careful to 
re-select the original "pretty color icon" when you are done, or things 
that don't ask get what you had selected. This leads to things like a 
'1;37' background with '1;37' text, which, as you noticed, makes for 
'invisible ink'.

What I think you want to do is tell the CUI that '0;30' should be 
'255,255,255', '1;37' should be '0,0,0', etc, so that you will have 
something that is legible in all circumstances (unless something is 
asking for the same foreground and background, in which case you were 
screwed even before you started tinkering - but I haven't seen any 
Cygwin programs with that problem).

If you change the numbers as I mentioned, then anything asking for e.g. 
'1;31' will show up as whatever you changed 'bright red' to be.

This implies that you have somehow set the default background color to 
'1;37'. Less is then displaying text as '1;37'. I don't think you can 
change less without hacking it, but I don't think you want to; if you go 
this route, you'll be chasing down this issue in dozens of programs.

I am not sure what you would accomplish by editing termcap; I don't 
think termcap has any control over this (except maybe you could disable 
text attributes entirely, but I'm not sure what the point would be... 
and just setting TERM to something like maybe 'dumb' would take care of 
that).
