showrgb and grep don't (afaik) depend on the terminfo.
wrap-around issues with cygwin could be due to stray carriage-returns
(guess). You should be able to test this by redirecting
showrgb | grep black >foo
(also check the contents with vi, etc.).

Foreground/Background set the class names (usually foreground/background
are preferred). Setting the class names can produce some odd effects.
I haven't looked at that for a while, but do recall some comments that
it has the effect of disabling ANSI colors, e.g., for text.

...which is odd - the only thing I could think of is that /usr/bin/clear
on cygwin is a termcap application, and the /etc/termcap is modified to
set colors explicitly (I've seen people doing that on other systems, so
it's something to check).
